I lose as much as I win . . .
This is almost certainly not true. It may seem like it for any small sample, but if you actually tracked all your bets, over a large number of bets you will most likely find that your total losses are a bit more than 1.9% of the total amount you have bet.
You also have to play methodically AND a whole bunch to lose that little over time. The real house advantage is that you're very likely to blow your wad before you can even get anywhere near breaking even.
