This is the raw device.

This is the first partition (or fs if unpartitioned) on that device.  It
obviously cannot be larger than the device unless there's some error,
but it can certainly be smaller.

It is quite common that a few sectors at the end of the device (or
between partitions) aren't used to keep certain constraints on the
layout of the device or the file system.
