Tunes/Music maintains its own internal metadata database, a copy of metadata stored in audio files. Every time when you edit audio metadata in iTunes, it writes it to its own database. Then it syncs the database with the metadata embedded to audio files.
Unfortunately, Rating, Plays, and there are few other fields that are the exception. iTunes/Music does not write or embed the content of these fields into audio files.
You can import the content of Rating, Plays and any other iTunes/Music fields with the Edit / Load Tags / From Music menu command.
