Yes, it is true that the probability will remain the same, but that is also okay because they will never think about the probability. They just want to keep playing slots and try to win a few dollars, and if they are really lucky, they can win a lot of money, at least more than the amount they have already won.
And gamblers also know their chances of winning will not be greater than the house. They will also not stop playing slots because they have found pleasure in playing slots. And when they become addicted to playing slots, they won't think about other things because it's not important to them anymore.
Yes, that's the tricky part.
When the gambler gets those feel-good chemicals while playing on the casino, that's the issue. Because the gambler will want to come back, and they will have to pay.
And the more they come back, the more they will be paying, until they just run out of money, and the music stops.
Nothing else to be done at that point basically.
