I guess it all comes down to what they mean by "basic understanding", "experience" and "familiarity". I am pretty inexperienced with modern web developer, but I still have a basic understanding what the difference AWS services do (ie I've read the description of them on the AWS homepage). I have experience with Vagrant and Docker (ie I've installed and played around with both and some point). I'm familiar with tracking systems such as JIRA (although not actually JIRA).

Basically don't read too much into lists like this. As long as you've heard of everything on the list and are good at two of the most import ones you're probably good to go.
