AFAIK it also includes ads in the News app and apps that load articles from the News app (e.g. Stocks app).
Their fine print also mentions the TV app, but I haven’t seen ads there, so perhaps they’re referring to content suggestions.
This seems to be confirmed further down the line in the fine print when it says:
> We create segments to deliver personalized ads on the App Store, Apple News, and Stocks.
I’d say the main difference between Meta and Apple is that the latter doesn’t combine data from different source and only relies on their own data (what Apple calls “tracking”):
> Apple’s advertising platform does not track you, meaning that it does not link user or device data collected from our apps with user or device data collected from third parties for targeted advertising or advertising measurement purposes, and does not share user or device data with data brokers.
