So my friend who got their S rank in one multi is a gambling addict, while I'm perfectly sane for farming everything I could to hit the pity 2 minutes before the end
Yes, people claim this. The reason is that they think of gambling as a legal or moral category. Gambling is that thing with PSAs about it imploring you to call a hotline if you have a problem. It's the same kind of thinking as "No, I don't do drugs, I just have a morning triple espresso, a few beers after work, and a smoke break every couple hours."
There definitely is some skill involved in poker and blackjack, but skill and gambling are not mutually exclusive. Like playing chess is completely skill-based, but if I also wager on the outcome, that's still gambling.
