What do you think of people who think you become a completely different person at 25?

I see this on reddit mostly. They say when you are 25 you can date and have sex with much older people but under 25 you get manipulated somehow.

I don't get this thinking, I barely changed when I reached 25 but some people think it's an age when you somehow suddenly become adult. It's weird to me.
