Yes, they do make a profit: https://gamerant.com/epic-games-store-revenue-split-explaine...

"Sweeney also said that Epic Games makes approximately 5% profit from that 12%, and this could grow to 6-7% as the store grows."

They chose 12% specifically as a balance between profit and undercutting the competition.
