Nobody here can do more than give you general odds, which aren't even consistent from state to state or between types of case. The figure which gets tossed around a lot, but which seems to be based upon impressions and not actual analysis of case law, is that lower courts are affirmed (meaning the appellant loses) between 80 and 95% of the time.
Nobody here can give you odds relevant to your case, as your chances of appeal depend upon many factors, including the facts of your case, what's in the lower court record, the mistakes allegedly made by the court, whether those mistakes are material to the outcome, whether the mistakes are of fact or law, and the standard of review which would be applied by the appellate court.
