I never met personally gambler winners but I saw them how they hit the jackpot on dice gambling before. It was on PD before one of my friends there who accidentally hit the jackpot and I think that was a huge amount. I know that was not successful because for me that is a coincidence and for sure he never does it again. But at least I witnessed the time that he won at that time that makes me motivated too in gambling.
In real life I do not met any successful gambler. The main reason for this is that I hardly go to any physical casino and most of the time i spend online on gambling. I do happen to come across few gamblers who did won some decent amount from gambling through online chatting. Sometimes i wish that i may be lucky too to win some big amount of money through betting & gambling games.
Your story is like me, i don't have any time for playing off line gambling games and the other reason i don't met the successfull gambler because in my local place just small amount of gambling games, so until now i still don't meet successfull gambler but i have chance to see successfull gambler related with cryptocurrencies.
