I doubt if there could be someone who is born with gambling talent, there is nothing like such, from what I've seen so far, I haven't met a consistent winner, everyone is always struggling with winning no matter how hard they try.
Even if there are lucky days, it does not even last longer, lucky days are always one day, I haven't encountered consecutive two days of winning, always one day of luck.
Imagine this, to be expecting a born winner, nah.
You have a point, no one has that inbuilt talent of gambling, it's one of the things that can be passed down through he genetics. This is a self developed habit that forms as a result of peer pressure, greed and other negativities. Gambling is a game of luck and nobody can be perfect in it. It's always scary when I'm on winning streaks because I know what's going to come next if I don't stop for a while
