Luck is very important in gambling, but skill is also important in specific games, like poker. New players can do mistakes when playing poker while older players know what to do in specific situations, means they can win more if they play longer. Other gambling games like roulette or slots can't be profitable in long term, as they are purely luck based.
Yeah, we totally can't deny skills in gambling., Some specific games like poker and sports betting and etc, we mustily use skills and strategy. But many gamblers are not agree on it, they think in every game of gambling, we depend on luck. But we prefer skills than they think we deny skills, It doesn't mean that we are ignore the luck or skills. I believe we should use both in specific games than we win.
