I typically don’t argue in favor of big corporations but I believe them, kind of. Apple includes a lot of things into their SDKs for free, which are paid on Google's platform. For example Apple Maps, Apple Weather, etc. components are all free and can be extremely expensive on Android (Google charging per view for Google Maps, for example). That is of course if you use these things in your app.

they could still calculate their profit margin: cost to build all their free SDK / profit from app store. Seems quite simple. Why would you believe them that they are not able to perform this calculation?
