Should I be worried that my crush calls me "fam"?

OK I've had a crush on her for a while and we are pretty good friends and we have a very playful/teasing friendship with plenty of physical contact.

We've been steadily becoming closer to each other (I'm not rushing anything). I used to be real afraid this was how she treated regular guys but she's been more proactive latley and she always calls my name if she sees me and we always have a "high five"/ or hand grab thingy its (people notice it and says its cute how me and her act).

So I'm a bit put off how she has called me " FAM" when thanking me sometimes. Its like code red friendzone right? She is white and girly so its unsuall from hee and I guess I called her FAM and even "bruh" first but still it hits me hard when she uses it. She might just be tryna talk like I do but... I don't know. Girls do you call guys fam?
