Entire Disk is 2TB but df shows a partition of 196G

[Noah]

Hi there,

When I built the main system drive - I built it to use the entire disk. 
It is an 2TB NVMe drive installed in the machine.  Why is only 196G 
showing up for the size of the  /dev/mapper/ubuntu--vg-ubuntu--lv 
partition.  Seems like I am not quite understanding what "entire disk" 
during the installation process means.

Cheers
