OP - you look just about as good as you can look for a chance at an OOS admission to UNC. I’m not sure what your legacy connection would be if you’re also 1st gen, and whether UNC would give it the same weight as a parent/grandparent legacy. Anecdotally, over the past several admissions cycles it appears that UNC has taken steps to admit more diverse classes, so being a white female may work against you a bit unless you have an additional hook along with that (LGBTQ?) Definitely go for it, but as others have said, fall in love with the hundreds of other wonderful colleges that would roll out the red carpet for someone with your amazing qualifications!
From the article that tsbna44 posted above re: Carolina legacies (this made me chuckle - Bless UNC’s heart and it’s ability to guilt it’s alumni into continuing to donate money!) 
“Sadly, I sometimes hear from alumni who insist that because their child or grandchild was not admitted to Carolina, they plan to no longer support their alma mater. I always encourage them to reconsider — not just because Carolina never wants to lose a member of our family — but because such a dramatic withdrawing of support won’t go unnoticed by their child or grandchild. I explain that they and their student have shared a lifelong enthusiasm for Carolina. Their student is understandably disappointed in not having the opportunity to attend Carolina in the fall, but I ask: Do you now wish to compound that sadness by making your student also feel guilty because you’re no longer going to support Carolina?”
