Yes, that's the size allocated to it. It will not change during the
lifetime of a program.

That's the allocated space for the heap. Half of it is used, the other
half is filled from the first one on GC (and then the parts will be
swapped). Note that this is the whole heap, not the size of the
actually live data, which will be less.
