Are first-attempt UPSC toppers real — and what's actually behind those rare cases?

Yes — but VERY rare. Verified first-attempt AIR-1 toppers in the past decade: Tina Dabi (CSE 2015) and Kanishak Kataria (CSE 2018). Both shared specific advantages: 2-4 years of pre-application full-time prep, elite educational background, and exceptional optional choices. The 'first attempt' label is technically accurate but the prep duration was 2-4 years before the form was submitted.
