Although I think what you say is partially correct, I will qualify a couple of things that many of you who comment do not seem to specify well enough.
There is an essential difference between the long term and the short term. In the short term, results are unpredictable, that is where what many of you call "luck" comes in, which is nothing more than short-term mathematical variability. But there is no such thing as a strategy. If the OP is thinking of valid short term strategies, there are none, but he can get lucky and come out a winner one night in the casino.
In the long term, there is no luck involved. The casino is always going to be a winner, and the player a loser, because of HE. And so if the OP by strategies refers to strategies to consistently beat the casino in the long run he is looking for an impossible.
