When a field group is deleted, are associated entries in the database deleted? Are corresponding rows deleted from wp_postmeta table?

No. Deleting a field or a field group does not delete _postmeta entries.

There is an old. long discussion about it here https://support.advancedcustomfields.com/forums/topic/flush-unused-custom-fields/
