There are some successful gamblers that become rich after they win and hit the jackpot prize of the game. If you are lucky enough to be successful with gambling then that is good for you, but not all of us have that luck to find success with gambling. So, better think twice before going to put all your income in gambling.
I dont think that there is any success in gambling. The result of gambling is always worst and you will lose everything in gambling. Mostly gamblers are also criminals because they can do any illegal activity for getting some money for gambling. Now ordinary people also gamble online and they are not criminals. On the whole gambling is bad and there is no success in it.
Maybe you are right that some people became rich due to successful gambling but mostly gamblers lose their money in regular gambling. It is wise and sensible decision to quit gambling when you win a big game. Take your money and go back to your home is your success, but if you continue definitely you will lose all your money and even go into debts.
