Talent is something that you are born with that takes a little effort to be developed or improved on... gambling is something that is learned overtime due to what you are exposed to and the only way to get better at it is by acquiring more knowledgeable..I don't really think that there's such thing as talented gamblers, gambling is all about luck and skills...when it comes to having it as a talent it's not possible
What you said is true because gambling does not require talent but rather courage and skill although everyone should not ignore their knowledge of gambling before entering the gambling itself. So I also think that gambling is very dependent on luck because it is much more feasible to expect through gambling because gambling does not require any talent for those who play it. Moreover, now everyone can gamble anywhere either through their smartphone or through other devices that can be connected to the internet, so talent is not needed at all.
