You are correct in thinking that there would be an infinite subset of universes where humans never evolved. However, there would also be a much smaller, but still infinite, subset of universes where humans did evolve. And there would be a muuuuuch smaller, but still infinite, subset of universes where the history of the universe and all of human history transpired exactly as it did in our universe, up until the point it diverged with the necessary changes in order to be relevant to the plot of the movie. That tiny tiny tiny subset is the only thing we talk about in movies, because otherwise it would be too confusing for general audiences. Hope this helps.

What always bothered me about multiverse moves is how a person’s life could be so different across universes, even though their ancestors lives must’ve been fairly consistent across universes or they wouldn’t exist. Hell, forget about whether you would be born, would humans even evolve? Would life even evolve? A lot happened between the big bang and your conception. A lot could’ve happened. I’m just talking out of my ass though

That’s a good point. A fraction of infinity is still infinity

Such movies generally explain it as there are other universes locally clustered to yours. As in, there are so many universes that some are only a few decisions/variables off yours

Although ones like Star Trek’s Mirror Universe are absurd. If humans remained that warlike and aggressive the timeline would be drastically different, with few counterparts existing.

One small change can lead to a totally divergent path. Think about it this way. You are supposed to meet your SO today at work. But you forgot to brush. No big deal. Right? Well your SO says hello, so you say it back and then she gets a whiff. Well end of conversation and that’s that. No wife. No kids. Not with her.
Or maybe you miss that buss that you barely caught. Or maybe you win the lotto at 19 and that changes everything for you.
You’re thinking wrong if you think lives have to be drastically different in every way for it to manifest as a whole new life. It can be the smallest thing but that tiny, infinitesimal thing can lead to a cascade of change or shunt people down an entirely different path.
Lastly, your ancestors would also be subject to these events, making all their lives very different as well.
Butterfly Effect.

right, but some movies show universes with very different pasts that still show a weirdly similar present. As you said, the smallest of things in the past should cause the present to be even more different, but in many movies that’s not the case

I often think about the silicon lifeform from A Martian Oddity because of how uniquely different it is from the carbon-based lifeforms we’re used to seeing even in science fiction.
