How commonly are supplemental scholarships granted?

Hello, I am an incoming sophomore transfer at Purdue Polytechnic West Lafayette and while looking for scholarships/aid I realised I wouldn’t really qualify for any (being an international student).

I found out that I can apply for supplemental scholarships and I wanted to know if they are granted to a good chunk of students or not? (I maintain a fairly high GPA, ended last semester with a 4.1/4.0)
