Fall 2022 - Stat/Biostat MS Profile Eval + Advice Appreciated!

[trying-my-best]

Hi everyone! I am a few years out of college and will be applying to masters programs in statistics/biostatistics this year.
 
I am concerned about my low grades in my math and stat classes (which didn’t improve over time as I would have liked), as well as the fact that I can probably only get one letter of rec from a professor.
 
At what level will I be competitive for any stat/biostat masters programs? I know that masters programs are easier to get into than PhD programs, but I'm just not sure to what extent. For example, I’ve been looking into UCLA’s biostat masters, is this reasonable? What about Berkeley biostat? Should I take any courses online or at a local university to make up for my current record?

Additionally, if I were to apply for a PhD program post masters, how would my undergrad record affect my application, assuming the masters goes well? Thank you!

I think for masters programs you have a pretty good shot at the top programs especially given you took real analysis and quite a bit of math.  I'd even think that you would have a shot at some PhD programs as well.
