AWA is not one of the elements that schools consider in evaluating your application... don't worry.
The point you should know is: you are a competitive candidate, but there are many other competitive candidates who apply for a Phd program. You have chances, of course, but every applicant has his/her strenghs and weaknesses. In sum, no one is sure to be enrolled in a program. As a result, the luck plays a role to determine the final outcome.
