In your story of course the person is someone who is never grateful and is included in the category of greedy gamblers, he gambles with small amounts but wants to get big wins, it is very unlikely unless you are really very lucky, and he also wants to get big wins but he is not ready to lose the money he bets and that is a very silly mentality in gambling, like a loser.

Basically gambling is an activity about winning and losing and that has been clear from the start, so until whenever there will always be something called losing money, so we don't need to be afraid but we must prepare ourselves to accept the situation and that is the reason why we are always advised to gamble with small amounts or amounts that we are ready to lose.
