First and foremost I meant you no disrespect. Your post here adds more context than your initial one, and I have in my time also seen these things you express in your latest post.
Just as you added more context, perhaps I should have added more to my initial post regarding the situation I spoke of. My group, the “older gamblers”, while we play all games, the main focus of our gambling sessions is one pocket. The younger players I spoke of, aren’t kids, more 20-30 something’s, just younger than us. They play well, just rotation games though.
The interaction actually started with them talking

when they would walk by, just loudly enough for us to hear, about “old farts that play 1 pocket because we can’t see, or play we’ll enough to play 9 or 10 ball anymore”. The chide I referred to in the match that unfolded was one of us replying “well if you want to actually bet something, we can play some even 9 or 10 ball right now”. That’s how the match came about, they put up the best of their little group, pooled their money to post the stake, and got schooled.
So as I’ve now provided more context you can see that it wasn’t quite what you thought it was. We gamble because it’s always been our way from those of our speed and our era. We can’t just quite understand them, they play well, more than well enough to get into action, but they rarely do, or as I initially stated, only for peanuts and amongst each other. It’s lost on us, it just appears that as time has passed, the younger generation is just different than ours.
