I know that as gamblers, everyone can relate to this question, as we have surely experienced it in real situations.
Suppose our bankroll is $100 and it has already grown to $500, would you quit or continue? Conversely, if with our bankroll, we are down to $10, would you still continue or save the remaining $10? I used specific amounts to make it easier to discuss this situation. I understand that we all gamble with different amounts based on our income, but consider this as an example. You can mention any amount you want based on your personal experience; it doesn't matter.
It's easier for people to stop gambling after losing a lot, especially after playing for years, destroying their lives and falling into addiction. In most cases, people stop playing forever only when they have lost everything and no longer have the money to continue playing. These are very small cases in which people play and even though they have the money to continue playing they manage to say: "
tomorrow I'm going to stop playing forever" and tomorrow arrives and they actually stop playing and are fine with that decision. In these cases, it shows that the person had not reached the stage of becoming dependent on gambling
When people win a lot of money gambling, the tendency of most people will be to continue playing and then lose everything. This happens to people who play slots, sports betting, all card games. only people who participate in lotteries and when they hit the jackpot and become rich they immediately stop playing forever, but in most cases they spend all their money on nonsense and become poor and then go back to buying lottery tickets and never win again
