If by 'you', you mean an individual, then perhaps...
If you mean anyone/ everyone, then you are dead wrong! The place would not exist if it wasn't taking more than paying and it takes more losers than winners to stay afloat.
Oh definitely an individual. Anyone can win if they work hard an study. But like Johnnyt says, the track doesn't care who wins or who loses. You are not betting against the track. You are betting against the other horse players. The track takes a set amount from every bet. The more that is bet, the more they make.
