When we enter gambling, big gamblers and small gamblers are the same here and maybe the difference is the amount of money they are playing with. But we also cannot escape the risks, I mean when our amount of money is large, the risks will go hand in hand. About winning, it goes back to luck and indeed in gambling luck really feels very thick. Even though there are several types of games that require skill and analysis, they still require luck. If gambling was only for the top players, maybe it would be jealousy among users and of course it would hurt the casinos themselves.
