I get what you mean, but what you said means something different, in a way that leads to an interesting question.
The odds are not supposed to be completely random. The odds are supposed to fixed in most (all?) casino games (and in most non-casino games). It is the outcome that is supposed to be completely random in casino games, distributed according to the fixed odds.
That raises a question. What would a game look like where the odds were random? The odds are determined by the rules, so would the game have to have rules that are changing at random?
But if you are given the distribution of the random numbers that determine the rule changes, you could still work out the players odds for the overall game. So do we have to have the distribution that the random rule changes use be completely random, too? But the distribution used to generate the random number used to pick the distribution for picking random numbers to drive the rule changes...do we need to pick that at random....is it going to be random distributions all the way down? My head is starting to hurt...
