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.
Of course working on your career, studying and working hard does pay off. People these days want easy money and focus on get-rich-quick methods and end up gambling their money. I never gamble as I consider my money as something is adore and wish to use it do something good and not throw it away. Many rich people even have excess money and like to gamble since its simply surplus money, while poor people like me like to earn as much possible by clean methods and use it slowly in order to lead a happy and peaceful life.
It seems that most people here are addicted gamblers and will most probably disagree with me but it is just my opinion.
