The most probable scenario is that the gambler ends up even poorer than before.
But to prevent that from happening, you have to limit your balance for playing, that is, if you have little money, it is best to limit the money for playing and not commit all your money. Personally, that is my strategy, and once things work out, well, otherwise what can happen is that once you lose, you can leave everything there, not bet any more, and that is the most correct thing to do, but you have to have the necessary discipline to not deposit any more money.
I think limiting bankroll for these more degen activities or having a limit to play money is a wise thing to do
at the end of the day you'll have a simple tool to protect you from yourself and from your desires
even if you want more money to play if it's not there right at the moment your urge may subside and you'll be able to control yourself.
