Callously, when the survivors look back and decide to call it one. As far as I know there isn’t an agreed upon definition.
WW1 was originally called the War to End All Wars, I think, by many at the time. WW2 eclipsed it by taking place on at least 3 continents and across every ocean. Both are also known by other names that depend on the region. The US Civil War eclipsed both in the number of casualties. The Ukraine war isn’t likely to break records like that.
Could very well be American casualties only. I didn’t look it up. I was remembering a history class where we were discussing the effects of illness and disease during wars some 20 - 25 years ago. I do remember that our teacher’s statement did not include those killed in the concentration camps, but did include those lost to illness and disease.
Of course, Alabama school, it’s entirely possible that the lesson was complete nonsense.

Nah, from a solely US perspective it's correct. There were ~1.6 million military casualties in the civil war, and ~1.07 million in WW2. But there were a few more parties involved in WW2, so it's kind of weird to frame it as less bloody. If you include civilians, estimates range from 70 to 85 million dead worldwide (not including the >20 million wounded soldiers and unknown number of wounded civilians).

I'm maybe misunderstanding you here, but as far as I know there were about 100 times as many people killed in WW2 as in the US Civil war. 60 odd million vs 600,000 or so.
