Concern regarding HireRight and Background Check Verifications

So I just got a job offer for a role that was finally related to my studies. However, for two of my experience I added on my resume, they were project and internship role with a small business and were all unpaid. Also were roles that are very relevant to this position. I don’t have any proof of payment regarding those position, and only added my food/retail positions where I was paid. The recruiter called me regarding the position and whether I had year of experience working with certain skills for the retail/food sector and I said no but on my project I did. She said okay she will get back to me but guys, am I screwed?
