Even when they do, that doesn't mean they understand the process. Some times you can get by with that (not understanding the process) and other times it will bite you.

I had a hard time training people to use phase gauges and runout gauges because they wanted to look for specific numbers on the dial since they didn't understand what they were actually looking for and why - you can't pay attention to what the numbers are, you had to pay attention to the difference in the readings because the gauge is calibrated but the part and maybe even the table or clamp is not, and badly warped parts give vastly different initial readings anyway so you have to find only the degree that the part is out of phase or how much it is wobbling so you know how much of an adjustment to make to it.
