They mean the same thing.  I think slim chance is literal, that is your chance is small.  I think fat chance is sarcastic, that is you have no chance, so fat chance is just a joke.  Does this help?

Your teacher is crazy and using words that are not correct.  Though I believe that they mean "untwister".  Please tell your teacher to use correct terms.  If you want to impress them, tell them the "untwister" is actually called a topoisomerase.
