See zpool(1M):
This command reports actual physical space available to
the storage pool. The physical space can be different
from the total amount of space that any contained
datasets can actually use. The amount of space used in a
raidz configuration depends on the characteristics of
the data being written. In addition, ZFS reserves some
space for internal accounting that the zfs(1M) command
takes into account, but the zpool command does not. For
non-full pools of a reasonable size, these effects
should be invisible. For small pools, or pools that are
close to being completely full, these discrepancies may
become more noticeable.
