No, you will never be at 0$, even if you lose all you bets, you will always have something left because you win cash with your picks.
25$ 1 on 3
45$ 2 on 3
70$ 3 on 3
so lets say you have 1000$ before an event and you lose it , unless a terrible almost impossible 0 point in an event, you will have a little something left because you will have won some cash with your good picks.
