I would wager most Americans would not even be aware of that distinction. In popular discussion, they're the same thing.
So if school kids are being taught "the WW2 era American internment camps should be called American concentration camps," they're actually being mislead. The lesson can't be oblivious to popular understandings or less precise popular usage.
It's also worth noting that strategic obliviousness to the difference between popular and technical definitions is a time-tested and effective way to lie and mislead, because it lends itself to a fallacious but effective motte and bailey defense, which also exploits embarrassment over not wanting to seem ignorant and prejudice against people who appear ignorant to silence challenges.
