I believe there is no such thing as gifted gamblers. That is why gambling is called a game of luck so there is no gambler anywhere that can claim to have never lose a bet a so for this reason there is no gambler that is gifted rather we can say there are lucky gamblers because of there frequent winning and such gamblers can not be described as been gifted because at times they do also lose .No gambler is born with a gift of gambling so gambling is purely based on luck, irrespective of how frequent or lucky a gambler is.
I agree if it's gifted in a way that they are blessed with extreme amount of luck. But there are some that are gifted on skills in gambling. Like those professional poker players, you don't just need luck to win in that game. You should also be good at bluffing your opponent to gain advantage. They don't have 100% win rate but they know when to bet big or small.
I'm quite confused about the OP's question and the title of this thread as they have separate topics but to answer the main subject, I started to gamble when I was exploring this crypto space. I was looking for more ways to earn bitcoin besides from faucets and stumbled to a dice site. I deposited some amounts from my faucet earning with the thought of giving me a huge return then the rest is a lesson for me to remember when gambling.
