[ubuntu] Partitioning

I recently installed Ubuntu Server 20.04.1 LTS. I had it automatically partition my drive for me. I noticed that my root directory shows the following:

Code:

Filesystem Size Used Avail Use% Mounted on /dev/mapper/ubuntu--vg-ubuntu--lv 196G 6.1G 180G 4% /

It is a 1 TB WD HD.
Doing a fdisk on it:

Code:

Device Start End Sectors SizeType /dev/sda1 2048 1050623 1048576 512M EFI System /dev/sda2 1050624 3147775 2097152 1G Linux filesystem /dev/sda3 3147776 1953521663 1950373888 930G Linux filesystem

Which present a few questions. What is sda2? I assume that my root partition is on sda3. Why is it showing a size of only 196G available? Does that have to do with LVM? Will it automatically grow in size as need be? Lastly, do I really only have available to me ~930GB out of the 1TB?
