They'll usually refer to casualties as a short-hand, since it's easily quantifiable, but even that's not the entirety. Non-combat dead as a direct result of the war (through stuff like starvation and disease) and destruction of agricultural and industrial capacity are taken into account by most people.
So, while the numbers you posted have more American casualties during WWII than the civil war, few people would argue that WWII was more devastating for America (though it was obviously the more devastating war overall), because the US came out of WWII relatively unscathed.

It's why most people take more than just casualties into account. Once you account for the fact that a) the Yankees had more people due to more immigration, b) the north was more industrialized so it was easier for them to replace lost equipment, and c) a vast majority of the battles were fought in Confederate states, which completely demolished their agricultural base and what little industry they had, it makes a lot more sense. The American revolution is the more counter-intuitive war, since they pretty much just won that through war fatigue and French intervention.
