Being a PhD student at UCLA (or over public universities) was arguably risky in the best of times. When I applied to grad school a decade ago, I got an offer from UCLA Math and it was notable that funding was not guaranteed beyond the first year, meaning you may need to look for your own funding. Same thing with the offer from Berkeley Physics. In contrast, the private universities like Princeton guaranteed funding throughout the normal duration of the PhD program (you’re welcome to bring your own grants, but if you don’t and can’t find an advisor/lab to provide for you, the department with fix you up with TA jobs and stuff). Now it seems the public institutions got 100x shittier still (not saying private ones aren’t in a bind).
