I think that for such players the main goal is no longer to hit the jackpot but simply to win back what they lost before. And in gambling this becomes a huge trap when you focus only on trying to recover your losses. People who cannot accept their previous defeats and just move on will fall into this trap and constantly chase their losses. But if they have already experienced big losses before I doubt anything will change for them now. They will keep losing although what they really should do is just stop.
Dude you have mentioned a very important point. When we go to recover our lost money it is really a trap. We go to recover the money and invest big amount of money in gambling. In the end it turns out that we have lost all the money. I have seen many gamblers go bankrupt like this. They were very experienced. But even then they failed to recover the loss and lost all their money.
But I will mention one point that when we are too greedy it is also very harmful for us. Many times after winning big amount of money we think that our luck is very good today so we invest more money in gambling. And at the end of the day we go home empty handed. So I do not see any need to take extra risk in gambling. We should stop even after we win money and we should stop even after we lose money.
