Number of views is sometimes meaningless. It can include your OWN view, or the same person many times, or a bot. Or even someone searching on the web, and not even registering, which is VERY common.
Anyway - Jesus is of course, illustrating that it was the same as Jonah, who was considered a prophet, even though among most people, they just know the fish story.
HOWEVER - it was Jewish traditional belief that the soul remained with the body for three days and three nights - so that if Jesus was dead that long, he was most certainly dead. If he rose prior to that, it would seem less a miracle.
It's also why Lazarus' rising from the dead was miraculous, because HE was dead for four days (or at least, had been entombed that long).
