There’s some features of a Plex Pass that will be shared with users.
E.g. if this is Plex Pass features for your server (e.g. online extras, on-demand subtitles…).
Plexamp however requires the users to have their own Plex Pass.
I don’t know if this will change at some point.
There’s a feature suggestion asking to make Plexamp at least available for managed users you created for your own account.
