Unless by "won" you mean the court dismissed, or allowed the creditor to dismiss, the case against you without prejudice. In that case they could re-file. Otherwise, a judgment in your favor is final, and establishes the legal bar of "res judicata" which bars further prosecution of the case anywhere.
I agree with my colleagues. However, I'll add that a judgment is not final until the appeal period has expired. Typically after entry of a judgment, there is a certain window of time which allow for an appeal.
