You are correct in that AM frequency is generally labeled in khz... in the US the range is 535-1605 kHz
which means the parents statement about AM being "around 1MHz" is a fairly accurate statement, more accurate would be 1MHz plus/minus ~600 kHz.
Ultimately weather something is measured in kilohertz, megahertz or gigahertz, is a matter of scale, is something oscillating at of thousands of time per second, or millions, or billions?
Anyone who isn't from the US probably needs to fix their intermittently failing shift key, though. SI actually assigns meaning to capitalization in units and there is a big difference between mHz and MHz.
