maybe you could read this article you seem to so wrong and yet so adamant about it (isn't that the case for most who are wrong?).

End-to-end encryption
For additional privacy and security, many Apple services use end-to-end encryption, which encrypts your information using keys derived from your devices and your device passcode, which only you know. This means that only you can decrypt and access your information, and only on trusted devices where you’re signed in with your Apple ID. No one else, not even Apple, can access your end-to-end encrypted data. End-to-end encryption requires
two-factor authentication for your Apple ID and a passcode set on your devices. Some features using end-to-end encryption may require up-to-date software.
Not sure where your info comes from (or doesn't), but fact checks work
