my opinion is the opposite of yours. just few people can win big in gambling just by pour luck. the amount of talent gamblers build their ways upon skills is larger.
Actually it really depends on what games that you are playing. For skills games you can choose poker but it really needs a lot of experience but most people dont have enough experience that is why most of them are playing luck games like dice. Talent gambler is not so much compare to people that play lucky games but if you compare the result talent gambler is much more winning rather than lucky games player
I'm not sure about talented gamblers, because I haven't met anyone of them. There were many people who claimed themselves as the good talented gambler after they won some bucks, but in the end they got lost too.
