Per page 19 of Apple's FY 2019 annual report [0], the net sales for the 'Services' category (consisting of the following) was $46.291 billion.
> Services net sales include sales from the Company’s digital content stores and streaming services, AppleCare, licensing and other services. Services net sales also include amortization of the deferred value of Maps, Siri and free iCloud services, which are bundled in the sales price of certain products.
Undoubtedly, the App Store makes up a large chunk of that $46.291 billion, but not all of it. We don't know how much money Apple actually makes off of the App Store. For all we know, Apple attributes 50% of the iPhone's profit margin to "Maps, Siri, and free iCloud services" which would dramatically skew the numbers. Services also includes digital media, AppleCare, and licensing which are all non-trivial sources of revenue.
