Of course you could make some profit in the short term and that is basically what the gamblers are hoping for, gambling for one hour per day and making just 5-10 dollars per day using 100-200 dollars and just keep doing that. However, what they are not understanding that long term losses equals to that 200 dollars as well.

So, you make 10 bucks a day for 15 days, on 16th day you lose all 200 and that is how casino makes the money, you think you made a profit, after all it is 15 days in a row and some people even increase the bankroll to make more money as well, some are smarter and do not change whats working. In the end casino always wins, it is mathematically impossible, but I guess scripts would take the blame out of you, at least it won't be you that lost the money, you can blame the script for losing all your money.
