Math itself says that you will lose 1% of what you're betting(in most sites as they have 1% edge), no matter what strat you are using, in the long run. So no, there is no surefire way to know if you'll win or lose the next bet. The best thing would be to not gamble at all, as you would still be at 0% win or loss, with the second best way being withdrawing while you're ahead.
