Perhaps, but house advantage ensures you will keep losing in the long run. The only thing keeping you from a guaranteed win in the long run is the table limit. I ran some simulations a couple of years ago to test some strategies - it was quite shocking to see how common losing 17+ in a row is. Losing 6 in a row is bound to happen every few rounds due to martingale system relying on a lot of 'small' rounds to scrape in winnings.
