Preface: I know nothing about cars, like nothing at all. In car movies they always rev their cars to be cool, but I’ve heard people irl say it’s bad to do. Is it? If so, why? Explain simply please because I don’t know enough about car mechanics to understand otherwise; I don’t know car terms either.

Have you ever run downhill as a child, and at some point your legs can’t keep up and you fall face first? That’s what your engine mechanism are doing at the rev limiter.
It may not break it all but for sure doesn’t help to make it live long. Each engine has its own limits and it may be more or less catastrophic.
The more sporty is the engine the more care you have to use, eg: sport motorbike engine may explode when revved for minutes.
Last note, as others say, it is a lot worse if the engine is cold.
