Your win is based on luck wether you are playing slot or poker. I think this is what majority of female gamblers understand and that is why they don't bother going for skill games. One disadvantage of skill games is that, when losing it seems that you didn't do something right and that can make you to continue gambling hoping you will get it right in your next game securing more losses.
It is good that a gambler relies more on his luck than the skill he has on that game so that he can stop playing at the right time to enable him reduce his losses, otherwise, he will incure more losses if he believes in his skill because luck supercedes skills all the time in gamble.
If your luck was the most important thing when playing a skilled based game, then we will not see the same poker players reaching the final table and earning first place on so many poker tournaments, so while being lucky is without a doubt important, as it can give you an early advantage you can later capitalize, at the end the your skill is what matters the most, since it is your skill the main difference between yourself and other players.
