Why does my AWS instance have much less memory than listed in the specs?

I'm running a Cassandra cluster on a trio of EC2 i3.large instances. When I run the linux command df, I get the following:

It says that I have 34,732,828 1K blocks in total. That equals approximately 34 GB. However, the AWS website lists the following specs:

Why do I only have 34 GB if the instance has a 475 GB SSD?

Instance Store Volumes are not mounted by default. For i3.large instance type, it will be attached to the instance as device /dev/nvme01n1. It is the user's responsibility to format the device and mount it.

Use this command to list the attached devices

sudo fdisk -l

Refer here on how to format and mount the device.
