Yes. Their privacy policy is very clear. They’ve put so much effort into providing privacy features, well before every other developer in the industry, that they’ve built their customer base on it. The class action suit that they would face for compromising that policy would be massive, and they would hemorrhage customers. They have strong financial reason to maintain their word. If you ask for your GDPR compliant abstract from Apple, it’ll only include your name, phone number, and billing address.
From a security standpoint, the privacy features are top notch. They use 256-bit AES encryption for iCloud, iMessage, FaceTime, Apple Wallet, Find My iPhone, HomeKit, FileVault, Secure Enclave, and now Apple Intelligence. Apple operating systems use a UNIX kernel design, keeping the application layer independent of the operating system layer, allowing full sandbox control and requiring user authorization for any API access.
Plus, nerds love to try and find chinks in the armor. In the event of the inevitable vulnerability, Apple is always quick to release a patch.
Edit: You asked a question about Apple products outside of an Apple instance. Look for the ones with all the downvotes to get a real answer from Apple customers. PC/Android users love to condescendingly reply to and downvote Apple supporting comments. I think it makes them feel superior. Lol
