Why can’t people go to the casino playing roulette and bet on black, and if they lose, double what they lost and bet on black again until they win?

If you bet $100, your odds of winning are around 50% and if you lose, bet $200, and so on and so forth until you win, and then cash out with a guaranteed profit. Assuming odds of black are 47.37% as per American roulette, your odds of not winning a single one after 6 tries are 0.02125 (I think) and decrease exponentially after each subsequent try.

If the odds of winning were actually 50%, and a lot of people did this, this is what would happen:
-Most would profit $100
-A few people would lose all their money, roughly equal to the total amount everyone else won

The fact that the odds of winning are slightly less than 50% only makes it worse for the gamblers. Basically, you have a high chance of getting a small amount of winnings, and a small chance of losing a huge amount of money. Gaining the small amount won’t affect your life nearly as much as losing the huge amount, so why bother?
