Grades and my future

Hi there. I’m currently attending University of Central Florida. I have a 2.7 cumulative gpa and try to get into the AD/PR major. I got a D on my first Stats test(I tried really hard but the hurricane really screwed up my schedule.) At this point I don’t think I can get into the program. I spoke to my professor and she said that the degree really doesn’t matter and I can go to other majors and still work in advertising. My passions are media and despite my professor, I’m still terrified of not getting into the program. Should I still worry or am I fine?
