You got good advice including to call the schools and see if you can get more money. Bryn Mawr has nearly a billion in its endowment so might be able to give you better funding. It does happen sometimes so I would call and ask all the schools.
My friend’s son majored in math at a local regional state school and got into both stats grad programs to which he applied (both very competitive programs) and plans to get an M.A. My understanding is that data science/stats is a field with a lot of jobs and not enough people to fill them, but I would be wrong. If that is still the case, I’d err a bit more on the debt because of the high chance to have a good job. I’m sorry you have this added stress and hope things work out for you.
