Gambling is for fun. Higher bets can get you higher wins but can also make you go bankrupt. You cannot become rich with gambling, if you want to become rich work hard and focus on your career.
Agreed gambling is just for fun and not to get rich as on our wish there, it's impossible to make bankrupt the casino being greedy while betting there, I don't think high amount of bet will come with guaranteed win but it can take us into deep trouble in case of addiction by playing continuously.
