Do you think I have a chance?

Yes. I was accepted on to a taught MSc course with some bad grades from undergraduate (some below 40%). I got a distinction and now I'm a postdoc.

Yes.

I was accepted to a masters program with some bad grades on my undergraduate transcript, some courses with less then 40% marks. In graduate school I got a distinction and now I'm a postdoc.

Doing poorly in a single course won't ostracize you from all graduate schools.
