Gambling systems always play into human psychology, and are always not in your favor.

So is poker not gambling? Mahjong? When it’s 4 people playing together (not at a casino, for instance), how can it always be you who has worse odds? That’s of course rhetorical; you actual have equal odds, barring cheating or simple skill differences.

And once you make “playing a game that you are likely to lose” as the litmus test for what is gambling, why would you play any competitive games? Half of a competitive bracket has to lose more than they won, by definition.

You are conflating gambling as it happens within controlled, predatory, capitalist institutions, with Gambling as a concept. Gambling is not immoral or harmful intrinsically, but gambling institutions that intentionally exploit addiction to gambling, are. Institutions that intentionally exploit addiction to alcohol or cigarettes or hoarding or whatever, also are. But it doesn’t make alcohol as a chemical compound itself, immoral.
