University of Washington application

Im a high school senior graduating in June 2017, planning on apply to UW (In-state)

My current Stats: -GPA of 3.65 (Freshmen-Junior)
-SAT 1120/1600 (RW:560 M:560)
-EC: (Minimal) Was in a club during sophomore year, 100+ hour of Volunteering
-Taking 2 AP in my senior year

I guessed that im too naive hoping to be accepted with such mediocre stats after doing some research online.

Whats my overall chance of getting in and at which area I can improve on to boost up my chance of acceptance? What do you guys think?

I say go for it.
Your stats are okay and you are in-state so you should have a good chance. UW is a really good school, so you should try.
