If any event has useable information, then intuition can play a role in decision making. A bias in the dice, either inherent or introduced would fall under that category. As would decisions in the game of poker, or playing BJ. All of those events contain useful, or potentially useful information. Pure random chance provides no useful information concerning future events. That is the definition of random chance. I will concede that there is no perfect random number generator, and that "pure" random does not exist in most random chance games......but most imperfections are undetectable by an observer. So for all practical purposes, they do their job more than adequately.....just ask the casinos.
