Hi,
While checking with df -h, it's showing the used space is 94% on root (/). If checked with du -sh, it's not showing the used space.

As an addition to what others have already said. You'll also miss things "hidden under mounts". That is, if you had 5G in /var/log on the root file system and then mounted a different device on /var/log, then that 5G would still be there but invisible.
Also, /dev/mapper/centos-home, HOME?!, on /var/log?
