Yes, except for sports bet which is also considered as gambling. Most games that used RNG, provably fair are obviously luck based, but sports betting it requires at least some knowledge for you to win not just betting on any team or players.
Yes because in sports book you need a little knowledge as well , pure luck will not be so effective because it is a kind of match that will run in hrs and there's a strategy and team that are playin that is why sports betting is my favorite because I am not lucky enough to win in most of the gambling games and I want to challenge myself on how will I choose the team that I will put my bet with.
