That's what I think. The same as the fingerprint on the cell phone. I'm not a big fan of making my data accessible to private companies and, for example, I don't have my cell phone locked with a fingerprint even though I could. But I don't think it's as bad as it might seem at first glance.
Your fears seem a little paranoid to me. You are probably using the latest camera phones? After all, biometric data is collected not only by fingerprints, which, by the way, can be easily faked, but also by ordinary photographs, and you may not be aware that when you look at the phone, its camera is working. Some apps can easily identify the face and even the retina or iris of the eyes. How much information is sent about us to Apple servers?
Therefore, we should not panic so much if we hear here and there about various kinds of information gathering. You need to have great knowledge and constantly monitor the news to be completely anonymous. I honestly doubt that most of the users who are here so actively protecting their privacy know how to properly protect themselves.
More often than not, this confidence looks like self-deception.
