My tentative understanding is that your GPA/academic performance as a master's student can mitigate a less-than-stellar academic performance as an undergraduate. How substantial, or marginal, the mitigation -- I don't know. But, if this is any hope to you, I had a friend who had a GPA somewhere in the 2's, went to law school for a year or two, then transferred to a terminal master's program, and he ended up going to Michigan for PhD (not going to divulge his field or anything). Point being, that there is hope. Now you really want to have strong letters ready for whenever you make the decision to apply to PhD programs. Hopefully your program is 2 years, instead of one, so you'll be able to form meaningful relationships with professors who have read your work and can assess your suitability for a doctoral program. But I imagine that you'll also have a professor or two who might be able to say something about this too from your undergraduate institution.
TLDR: get into a master's, do very well, figure out what you want to study concretely, and apply to programs that you'd be a good fit at accordingly. Nobody's chances are good, and prophesies in this enterprise are meaningless. Do the things you are passionate about and the road will naturally appear before you.
