"I certainly can't do that with horse racing no matter how hard I try."

That's because baccarat only has a 1% house edge. GGs house edge is MUCH higher.

Your own experiences aren't enough to prove whether you have an advantage or not when you bet. You'd need to do test a very large sample for a statistically significant result.

That said, you may very well win by just placing a couple of bets per hour. You are playing very few hands, so the variance will be greater. While the bets you are placing probally have negative expectation, you still have a reasonable chance of walking away a winner.

If you want to profit off gambling, why not pick up poker or something?
