I think Meta is reading your messages locally on your device and showing you personalized ads from the messages that are actually on your device. It's not uploaded on Meta's servers and not in anyway breaking the e2ee, because your device is one of the 2 ends. If you don't use Facebook or Instagram on your phone then no personalized ads is shown.
Everything above is supposition from something I vaguely remember but not 100% sure.
