Not understanding (json)
Why is the parameter of the callback function isn't (data)? Why is it (json)? Or am I wrong in assuming that that's the same argument?

As Shumin pointed out, the parameter name itself is not important to the operation of the function. But it's considered a "best practice" to use a name that represents the kind of content that the parameter is expected to have.
So in this case, naming it "json" is a bit more descriptive than just "data" if the contents are going to be in JSON format.
