There are many online demonstrations available, I'll just drop one here:

So, theoretically a casino can observe how you place your bets, then predict your next bets and make their own bets (they always go first) accordingly. The flaw here is if this algorithm is implemented too naively, it can be abused by players by making big amounts of predictable low-value bets, and then making a big opposite bet.
when Technology developed it is also one of the good factor for the development of any field if the gambling field accept the technology as an addition then it will be giving fun and extra involvement with the attraction of the the gambling very easily so that it will be acceptable for everyone.
