What exactly does "Priority Scholarship Applicant" of UR mean?

I am an international student who have applied to UR through RD process as a priority scholarship applicant. I want to thoroughly understand the program I applied to to ensure I make no mistakes in the webcam interview two days later. So is this simply going to increase my chance of getting a scholarship, or an individual program which leads to a better scholarship?

My understanding is that those that apply by that date have a better chance at receiving merit aid than those that apply just before the RD deadline.
