No one can beat the house, that's only true on games like dice where there is an edge but on skilled based gambling, it's not applicable.
I agree, that's why I don't want to engage with dice games and the alike because I knew that it would be hard to. If we will permutate there are so many combinations possible thus having a small chance to win.
Another tip, prefer games where the fortune is in your hands like poker. You can earn bigger here (if you are only good of course) because you would be the one who control thr flow of your cards.
