Batteries are rated in ampere hours. So the 24 pulling 1 amp and the twelve pulling 2 amps is probably offset by the 24V system needing 2 batteries. However the 12 pulling on the one battery will discharge it quicker than the 24V system would on the 2 batteries agreed ?

Indeed it will, but the OP is about a 12V two battery system, so it's on equal footing capacity-wise with the 24V system.
