That ~80% figure comes from an Epic argument. At that time Apple had argued the number was completely wrong and they were going to refute. I do not see any article online with an updated number, but it is almost certainly wrong. It is super annoying the tech bloggers never pestered Apple to reveal what they said they were going to. Historically Apple always has adjusted the quality of the product to match desired 35% margins and price points. I would be very surprised if the App Store is any different, although they may have had issues ramping up to eat that much money. Apple gouges users... but they tend to gouge consistently. The other 65% likely includes costs like advertising, cloud services, editorials, legal, fraud costs, WWDC, corporate overhead and the like but it far more than just hosting and evaluation costs. They may be blowing it on Apple TV+ content though. Services is a tricky number to nail down.
