I think your analogy oversteps -- it's really more akin to teaching people how to use a fire extinguisher, even though they're unlikely to ever encounter a fire. According to the ATF[1], there are more firearms in America than people. The idea that you might live your whole life and never see one is far from a given, though rurality vs. urbanality almost certainly affects this, as well as the carry laws in the area you live. The statement is almost certainly more true in somewhere like California than it is in Alaska, but in my experience, definitely doesn't hold true for "America" on the whole.
