No of course; I don't think anyone in here would advise not paying off credit cards. Honestly I'm probably projecting a bit as I had a hell of a time getting myself out of credit card debt, terrible place to be. in.
I don't want to sound all 'mumsy' but if you're tight on cash and have credit cards to pay off I personally wouldn't advise putting any money towards betting / gambling no matter how easy or guaranteed the results may be.
Obviously don't know you or your situation but paying off credit cards...
