There are lots of different card combinations that have different rankings. Refer to the game’s Help Menu > Activities > Poker, to see all the rules and card combinations.
You must play every table game for 100% completion and for the trophy “Hobby Horse”. For all other minigames check out the Red Dead Redemption 2 Minigames Guide.
