That just appears to be normal file system overheads. All file systems
use some of the total space available on a device for storing internal
structures and data (the file system's metadata). You'll see this with
any block device type, e.g. with a 64M USB key:
# df -h /mnt
Filesystem Size Used Avail Use% Mounted on
/dev/sdc1 61M 5.3M 53M 10% /mnt
