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.
Not all gamblers will get bad results at the end. There are also some people who can get out of gambling with satisfactory results. A neighbor of mine, in the past, was able to win some money by hitting the jackpot and was able to stop gambling afterwards. He built a business that until now can still support his family. But if we talk in general, yes, most gamblers will have a bad result at the end.
