iTunes/Music maintains its internal metadata database, a copy of metadata stored in audio files. Every time you edit audio metadata in iTunes, it writes it to its database. Then it syncs the database with the metadata embedded to audio files.
Unfortunately, Ratings, Plays, and a few other fields 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.
Import Audio Tracks from iTunes/Music

Show Rating and Plays columns
The Rating and Plays columns are not visible by default; therefore, you need to enable them. This could be done both via main or context menu 'View / Column / Rating' and 'View / Column / Plays'.
