For me there is a possibility to be rich in gambling but it will happen in one time winning and do not play again anymore because no one will be successful in the long run in gambling even it base on the luck but still no one can beat the house.
Yes there's a possibility that one can be rich in gambling and the chances and probability? there's odd that I've read that for every 50 million, there's only one that can hit the jackpot.
If you can create your own brand as a casino then that can be your life time success and you can say that you became rich in gambling but not as a gambler but as a businessman/investor.
It's just hard to be rich in gambling, that's the reality, by saying hard, it means 1/100 chance, and those who got rich are the smart gamblers who are willing to take the big risk just to reach their goal. Most of us wants to to make big money but are afraid to take big risk.
One example is that we bet small to win big and we want instant profit, that's how greedy and unrealistic we are.
Those who got rich are simply taking consideration the bankroll and they want it slowly but constantly making money, it's a long term process for them.
