The houses edge is to pay the running bills for the casino like staff wages, rent, upkeep etc etc etc, if there was no houses edge they wouldn’t be a casino.

It’s a tiny amount anyways like single zero on roulette lol, 1 single number extra like it’s going to effect my game in a massive way, It doesn’t and the best way to beat the casino which most people think is impossible is to sway the odds your way, bet responsibly, manage your bankroll, and learn to walk away.
