Yes it does clear things up. Let me restate the situation.  Modules are
separate programs that add functionality to the kernel usually on an "as
needed" basis.  One of the kinds of functionality that they add is
device drivers.  

Put another way, the kernel is a more-or-less fixed piece of software.
Drivers and other functions are also more-or-less fixed pieces of
software.  Modules permit flexibility between these two sets of fixed
pieces of software.

I could go on but I think I've got it.  The problem in understanding is
that sometimes writers get sloppy in distinguishing between the go
between, the module, and some of the end pieces (the driver).
