I don't find any success in gambling, besides it brings us being addicted to gambling and probably all your assets are gone. But I believe that there some people who gambled that base on their luck, and they still believed that they can win in every gambling they do. Much better while it is earlier minimize your self of being active on gambling, I must prefer to go in trading that is a lower risk rather than gambling.
It is good to try their luck in starting and if they win they should take away the money and enjoy it rather than trying too much luck in gambling which might prove to be costly as they may lose money as longer they play in gambling. Also getting addicted become easier as humans are greedy and want more and more money.
