Maybe im messing up the wording but it seems like b is assigned to a? The way they say it sounds like a=b but maybe im wrong at how im reading it?

Both a and b are variables. This means they are containers for storing data. a is the name of a container that stores the number 7 in this case. b is the name of a container that is not initially given a value to store (so it stores undefined by default). The instructions are saying to put the value (or contents) stored in a into b. So you are setting b to something, in this case to the value stored in a. In other words, you are making b equal to the value in a, and thus you would write:
