Years of gaming let you internalize a huge number of UX idioms that you rely on everyday, like left and right mouse clicks, hierarchical menus, hotkeys, text input, active and inactive UI elements, navigating documents larger than the viewport (drag/scroll wheel/scroll bars), and so on and so forth. Imagine how much harder it would be for your 14 year old self to install and run XAMPP or whatever if they knew none of these things. Imagine how much harder it would be for your 17 year old self to begin their programming journey if they didn't already know what a file is.
Looking back from the end of the road, those 0.1% might look tiny and insignificant. But there's a high chance you'd never go into programming at all if you didn't play video games as a child. Not because of the games themselves, but because they gave you early exposure to computers. If all you did was browse Facebook instead, the effect would be much the same.
"Acquainted with computers" is closer to endlessly strolling tiktoc now.
I used to work in a phone store where almost all customers were 50+. Explaining how to call a saved contact was a daily occurence to us, nevermind creating new contacts. While I do understand why this happens and have nothing but sympathy for these people, I wouldn't want my daughter to be like that at 18.
