cylinder/piston codes

I am trying to understand how you can mix/match pistons and cylinders.
The pistons come in group weights and seem to be in size ranges as well - matched presumably to variances in production tolerances in cylinder sizes, which also seem to come in group heights.
Have I got that right?
if that is correct does that mean that cylinders and pistons need to come as a matched pair? And cylinders need to be matched in group heights - at least per side of engine. But if your tolerance bore size was different, you would have a different group weighted piston?
I am trying to understand if I can replace one damaged piston or cylinder etc if I need to.
There is a partial set of new pistons/cylinders F/S in my country at the moment. But if I bought them as spares, am I able to source the matching cylinders and pistons?
Anyone follow this?
