No, it's just that some part of your RAM is used up for other things.
E.g. it may be used by your video card (if it doesn't have its own
VRAM), or by the kernel.

The opposite: it returns the actual usable size (of course "-g" makes
it round *down* to the nearest gigabyte, so you get a gross
under-approximation, but that's what you asked for).
