Unlikely.

If not then which can be more and approx. with how much percentage.
There is no rule.

You should use
Code:
du -xk

to limit du to the / file system.

You must be root otherwise du would miss files you have no privilege to read (Note: SCO du manual page states it is not required).

du is not taking into account usage df is measuring which is:
  • internal file system structure: superblocks, inode tables, journal, whatever the file system implementation defines
  • space lost by file system corruption (disconnected blocks and so on)
  • deleted still open files, if any
  • files that might be present in directories hidden by another mount, in your case /stand, /proc, /dev/fd, /dev/_tcp et /system/processor
