Unless things have changed recently, YC leverages former YC founders to do the initial application review. The founders that participate are from both currently operating companies and companies that closed or exited. So (if the review process has not changed in the last few years) there is a chance that a senior individual at a startup or an employee at a larger company that competes in the same space will see the details disclosed in the answers to the new questions about an applicant company's financials.
