I always hear stories of friends who always lose playing online gambling. I don't know what his purpose to tell his story to me. even it's clear, his story makes him look stupid.
Besides that, in another place, Many young people around to me still play slot gambling even don't have a job and always lose. I wonder where they get the money for deposits? and why they repeat that?. I don't know what the reason reason that doesn't bother them, they should have given up, and changed the game that makes them profitable. if I always lose in the game, I will change the type of game, example If I always lose on a slot, I will change the type of game like sports betting until my capital is back and try the luck again to the slot.
In my opinion, one of the reasons they continue to gamble even though they often lose is because the chance of winning is unreasonable. The motivation to want to get rich easily makes them continue to try to get money in any way in order to pursue opportunities to win in gambling games. The opportunity to win with a small bet can earn a very large amount of money, making them even more addicted and making it difficult to stop the habit.
They only seek and will continue to pursue victory without caring about defeat, that is the reason why they continue to gamble even though they always lose. Their curiosity and the lure of the opportunity to win large amounts of money makes them unable to control themselves, they will do anything to pursue victory, as long as their goal is not achieved they find it very difficult to give up.
Among many answers in this topic lately, this one makes most sense to me. People wouldn't continue gambling if it was impossible to win big. The problem is that the probability is extremely low, and to get one lucky winner there must be many losers, as in every zero sum game. On the other hand, I guess that the little bets also make them lose track of what they have spent, and that's why it is so easy to let themselves go if they don't set a limit on beforehand.
As you said, there is definitely a mix between curiosity and greed which makes them continue gambling. And the bravado of the lucky winners that we often see doesn't help either (as they did something epic, when in fact they just had unusual luck).
