Where in the DigitalOcean documentation/promotional materials did you read that you get 512MB of free memory?
Your droplet has 512MB assigned however 22MB of that is reserved by the droplet's kernel.

Didn't you read the pricing page of DigitalOcean?
512MB Memory
1 Core
20GB SSD Disk
1TB Transfer
I guess when I read the graphic you linked to, I interpreted it as stating that for $5/mo., I could purchase a VPS with an allocated 512MB of RAM.

Agreed. I interpreted it the same as you. Nowhere does it say FREE so I assume ALLOCATED.
