Chance me for UW?

I am a OOS state student in Texas and I would really like to expand my studies to the Northwest however I am worried about my chances for acceptance.

GPA 3.4/4.0
SAT 1310 (I’m going to retake it)
ECs
HOSA (2yrs)
Key Club (3yrs)
DECA (1yr)
UNICEF (1yr)
Spanish Club (2yrs)
Robotics Club (Vice President 2yrs)
Volunteering @ SPCA (animal shelter in Texas)

I’ve taken AP Lang, AP Human Geography, AP World History, AP Art History, AP Physics I, AP Comp Sci and AP US History.

I heard tuition for OOS applicants is pretty pricey. How easy is it to receive financial aid at UW?
