Roulette is not a scam in the sense that the casino is not cheating or rigging the game. However, it is important to understand that roulette is a game of chance, and there is no way to guarantee a win. The house edge in roulette is the percentage of money that the casino expects to win over time.
There may be individuals who have claimed to make a living from playing roulette, but it's important to approach such claims with skepticism and to consider the long-term statistical probabilities involved in gambling. It's generally not a reliable or sustainable way to make a living.
