And while I'm at it, Jesus said that the gates of hell would not prevail against His Church. If Catholicism got it oh so wrong and it wasn't made right until the Protestant Reformation, then doesn't that mean that the gates of hell prevailed for 1500 years? You might want to be careful about inadvertently calling Jesus a liar. Just sayin'.
That is an interpretation. There is so much written on Matthew 16:18 that I would have to start unraveling it for you.
"Moreover, as for myself, I also am saying to you, You are Rock [petros, masculine in gender, a detached but large fragment of rock], and upon this massive rock [petra, feminine in gender, feminine demonstrative pronoun cannot go back to masculine petros; petra, a rocky peak, a massive rock] I will build my Church. And the councils of the unseen world shall not overpower it." - "The New Testament (An Expanded Translation) by Dr. Kenneth Weust (NASB Translator).
When we look at a translation that is completely literal, it means "assembly" and not "church" and there is a whole different worldview that we read into the verse when we read "Church" because Church literally means the "ekklesia" (ek for out and lesia which is a form of called) or "called out ones" which is an assembly and not a physical structure or building:
Young's Literal Translation
'And I also say to thee, that thou art a rock, and upon this rock
I will build my assembly, and gates of Hades shall not prevail against it;

An example of this would be Revelation 20:8-9 where it says:
Revelation 20:8 And shall go out to deceive the nations which are in the four quarters of the earth, Gog and Magog, to gather them together to battle: the number of whom is as the sand of the sea.
Revelation 20:9 And they went up on the breadth of the earth, and compassed
the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them.
Camp means "assembly":
of the sacred congregation or assembly of Israel, as it had been gathered formerly in camps in the wilderness

There are at least two ways to interpret the Bible:
(1) Literal
(2) By what it means and not by what it says.
I can give examples as to where you have to depart from several passages where what it says is not what it means.
King James Bible
If I bear witness of myself, my witness is not true.
John 5:31
So you can't take John 5:31 literally by what it says because you have to go by what it means. If you take it literally, Jesus wouldn't be true if He testified about Himself. Jesus is talking about the Law and that the testimony of two or three witnesses is needed for a matter to be established in order to be true according to the law and that is found in Deuteronomy 17:6.
The second reason is that I've seen a Strong's Cyclopedia and it isn't one of those one volume Strong's references and sometimes when you look in the cyclopedia, you see an asterisk like "*" next to a word. That means the word itself comes from a word cluster and certain word clusters can have two or three hundred meanings but the translators then have to make an interpretation as all translations are an interpretation. They have to choose one of the two or three hundred meanings from a word cluster.
Another topic that is too long for discussion is the visible church verses the invisible church and it is true that you can't join a church because you have to be born into it. You might join a church but unless your spirit has been born a second time, you will die spiritually. You are looking at the physical interpretation of the verse instead of possible other meanings that scholars have found.
There are many expositors who apply this verse to the impending death of Christ, and there is some warrant for this interpretation. The Jews of New Testament times would have understood the "gates of Hades" to refer to physical death. Bible scholar Craig Keener notes that the "gates of Hades" in the Old Testament (Job 38:17; Psalm 9:13) and subsequent Jewish tradition refered to the realm and power of death.8
p. 107, "Reasoning from the Scriptures with Catholics" by Dr. Ron Rhodes.
Another possible interpreation, is that death in any form will not silence the church, the death of Jesus, the death of the apostles, the death of Christians anywhere. By Christ's divine power, the church will be sustained forever. But so-called apostolic successors are nowhere in view in this verse."
p. 107, "Reasoning from the Scriptures with Catholics" by Dr. Ron Rhodes.
So those are the easy things for you to confront but there is so much written against what you believe that it can't be true.

Make sure you answer each scholar in the commentaries for me in those two links so that I know Catholicism is true but the fact is there is a mountain of argumentation against Catholicism and I might talk with you so you know why I don't accept Catholicism but we can start there.
So no. You have an interpretation.
2 Peter 3:16 As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction.
