On the other hand I'm sure it's not just me who feels that way, but most of the gamblers who apply greed will feel the same disappointment when it turns out that their luck has run out and end up losing everything, but maybe some of them or most of them still don't realize that the action is actually wrong. There's nothing else and I admit it's better to just be grateful for your first win regardless of the amount.
Many gamblers feel the same as you. Even I feel it too. That's why we have to be able to overcome the losses so that they don't get bigger by maintaining good self-control so that we only enjoy gambling as entertainment. We also don't need to follow what other gamblers do by continuing to gamble because we are only responsible for ourselves. And if we have managed to win, we should cash out the winnings and get out of gambling immediately.
Gamble is of luck and no one can be an expert, when I mean expert, I really mean someone that can gamble 10 to 20 time a role and win the whole.
