You might compare a drunk person doing wrong things, and a gambler that is just so into the games that they are deciding to put more and more money in there to "recover" their losses.
It's a similar state really, where you are not thinking straight, and just want the benefit right now. In both cases most of the time you end up in a worse situation the next day after a day of bad decisions.
The biggest stupidity of gamblers is all-in bets in the desire to win back a loss. In this case, it is impossible to win, because after the next loss, this player will again try to repeat the same thing, and in the end he will still lose everything. There is no need to think that such people have any chances for a positive outcome.
