Who would win in a wrestling match, an average high school guy (non athlete) or the gymnast, Olivia Dunne?

My boyfriend and I disagree on the answer to this, so looking to get some more opinions. Totally average high school guy, like a junior. But the guy is not an athlete.

Rules of the match are like this: 30 minute match, pins and submissions count as points. How do you think this goes down.
