I think OP is also trying to know if there are people here who has actually become successful in business because of the experience that they acquired from gambling as risk takers which I already said in my first comment that the both experience are not usually the same and the fact that someone is a gambler doesn't mean the person can manage a business effectively. I doubt there's any tip as to how this can be possible, this works differently for everyone.
But I think the connection between risk taking in gambling and success in business is so thin, that its almost unseen. For example its the same as saying that professional boxing helps to succeed in running a business, because people would be afraid not to accept your point of view or proposal. When OP meant being a gambler, he probably has meant that its a person who can control emotions, evaluate risk, respect hard earned money, dont rush at taking decisions. No doubt that these qualities will be useful, but wont play a main role. For me success in business is build on knowing the market, but we cant say that gambler who knows the game will get any success in it.
