In fact, there can be no smart strategies in casino games that are completely based on luck. However, even there, strategies are possible. For example, the Martingale strategy. In general, this strategy is unprofitable, since you are playing a game with a negative mathematical expectation, if we are talking about games like roulette or dice, but sometimes luck can be on your side.
First of all, this whole quote is so confusing... I don't know if it's just me but I wasn't able to decipher -- even if I should have been able to, the whole sentence feels contradictory.. First of all, you're trying to prove that there's a strategy to play on casino games, but then, the strategies are unprofitable right? Well then that's as good as not having any..
Speaking on the martingale strategy, Paul proposed how insane it may look to wager double of the previous loss, but how it can possibly cover up the expense on just a single win. Whatever it is, this strategy isn't for a regular gambler as you'll need to have a better stake.
Any strategy that doesn't work as planned for atleast 35% of 100 tries is more of a "chance" then what y'all think it is.
I think that what he means is that even if a strategy can be devised, it does not mean that it is going to work, after all deciding to use martingale to try to beat the casinos is a strategy, it is just that it is not a good one and you will lose it all given enough time, also the reality is that some casino games can be beaten, but in order to do this you need to play live, an example of this is blackjack, since card counting can give an edge to the player, but unfortunately card counting does not work if you are gambling online.
