That's untrue. Demo:
root@kablamm:~# umount -v /dev/sdb1
umount: /dev/sdb1: not mounted.
root@kablamm:~# dumpe2fs -h /dev/sdb1 | grep ^Free
dumpe2fs 1.44.5 (15-Dec-2018)
Free blocks: 2721787
Free inodes: 792525
It seems too that you missed the point that gparted apparently
uses dumpe2fs to examine *unmounted* partitions.
It is also puzzling why you don't just mount any partition (that
you are curious about) somewhere and run 'df'?
Are you aware that you can easily access partitions that aren't
mounted automatically? Just mount them yourself, using the
'mount' command.
