There’s a wide range of pay levels there.
Those QA teams, automation people, production, level designers, vfx artists, tech artists, character artists, 2d artists, prop artists, gameplay scripters, etc are doing all that work just to put some pretty pixels on a 14 year old's screen. There's very little value there.
First off, adults play video games too. I think they’re actually the leading consumers, though I don’t care to look that up. Second, people like entertainment. Videogames are certainly no less important than movies, TV, or most novels. Entertainment can be important. Personally I find really hard videogames to be meditative and it’s bad for my mental health when I can’t get some time now and again to play some. I also made most of my adult friend group as a teen playing Halo together in a cabin multiple times per week.
I’m guessing you at least consume some sort of entertainment, so to say something like that is incredibly hypocritical.

As opposed to the 373rd X-as-a-service crud app with AI features?
As for the second part of your comment, well... yeah, I don't disagree with you there. That doesn't have any value either. Those people are probably not making that much money.
