That is not true.

Whereas Apple does collect information in its services like Appstore, Apple Music, Apple TV+,, Apple News, Books, it does not coalesce this information into user profiles and does not auction such a profile. Each store operates on its own here and uses the information this store sees like any other e-commerce shop (or analogue shop with customer binding programs) will do: address the user with ads based and what he did in this shop. I.e. Appstore does not know which books you are reading and which Apple TV offers you use and so on. This is all very clearly stated in the privacy regulations for Apple's services.

That is very different from what Google or FB are doing. They collect data from each and every service you are using, most of them not even offered by them, trying to track you across the net even if you do not have a Google or FB account, and create and enhance a user profile with this data consisting of several thousand data points, which is then auctioned on just-in-time platforms within microseconds whenever the user is doing something that opens up an advertisement slot (like e.g. a Google search or looking at his or her FB timeline).
