I would like to add to this that a player who wants to win and pay off debts thinks this way when he is in a sad situation and losing. But if he is lucky and really wins a lot of money, then there is a very high probability that he will continue to play and not go to repay his debts. The funny thing for me is that he doesn’t know why he continues to play to win $1 billion? Ahah. I want to say that some people's brains turn off completely and the player should not have the casino take over his brain.
The fact is that whatever situation you find yourself in at the end of the session can answer everything but there is still a lot of possibility for something worse to happen, which as you said, if they manage to get a win then it's not the end of the gamble but on the contrary they will be even more excited because they think that it's the right situation for them to overdo it in order to get a much bigger win and also maybe with the aim of paying off all the debts they have.
Not only that because winning also has a similar end scenario, if you are an addict it would be absurd if I didn't say that losing will make you even more curious about winning and trying again. Neither of these situations is better than the other, because they all have the possibility for anyone to enter the addiction zone consciously or unconsciously.
