Freshly Provisioned Cent-OS occupies a lot of space for "/dev/mapper/centos-root"

I created a fresh VM, however I started facing space issues as soon as it got created. From the du and lsblk command I see /dev/mapper/centos-root is occupying a lot of space. I tried running tree command on root to filter all files occupying large space. But the command takes forever.

How do I figure out what exactly is occupying space and delete them from system.

Here is the output of command.
