Unlike most other games of chance, especially the RIGGED casino games, poker has identifiable odds equal to everyone in the game not just rigged for the house.
A person well versed in odds for their hand, over time, will win against someone not as skilled. Skill will eventually override the chance factor. Math skills and the ability to bluff are very powerful factors.
I think Black Jack also has better odds that other games outside of what poker has. Love to play poker. My dad and mom loved poker it was the saturday night family game with a few specials invited. But it wasn’t for big money just for the fun...house rules.....2 cent limit, nickle on the last card, 3 bumps only....Good gravy I’m 73 and still remember house rules....oh yea, table stakes only...no leaving the table to hit the piggy bank either...I learned by watching and a few hints whispered to me by dad (I was his favorite LOL)
21 is somewhat like that.
