You can work harder and harder at a game but not end up better than someone with superhuman reaction times despite a lot of hard work. Also, the game changes due to patches and content updates - all that work you put in for a year understanding a mechanic might be for nothing at the drop of an update.
Even implying they do is blasphemous.
People love different things. It’s how you get masters at different crafts. Some people love solving things and some love creating... programming is both of those.
I can't, sorry. I'm pretty into playing games (though by no means a "gamer" in the sense that it controls my life, etc.) but I will often choose to program rather than play games in my free time.
You are a casual gamer, but in this context you are as much of a gamer as a random board game player is one compared to Magnus Carlsen.
Watching something compile, link and pass all your test cases after you add a new feature is a pretty big dopamine rush in of itself.
