What "intuition" are you talking about? Indeed we do a lot of things intuitively because the code for that kind of behavior has been inscripted in our brains for millions of years. (Well, technically not exactly in our brains, but rather in brains of the creatures that later had become Homo Sapiens.) Whatever those creatures where doing, they definitely weren't gambling, so intuition has nothing to do with this activity.
But I completely agree with you regarding luck based games. Hard work can't help you to win in those games.
