"Services" includes Apple TV+, Apple Music, Apple Arcade, Apple News, and iCloud+. I wish Apple broke out the subscriber or revenue numbers for each item in Services.
More like $20 billion, perhaps up to 25% of all services revenue. https://www.fool.com/investing/2023/02/21/20-billion-reasons...
Anecdotally, I cannot figure out how to cancel One without losing my iCloud photo library. As soon as I do figure that out, I'll be iCloud only.
Services also include the App Store, AppleCare, and the Google deal to be the default search engine in Safari, which is massive.
