I will add my $.02 for good measure. As a younger man before I got my first airline job I used to teach people how to fly. I was good at it in my opinion and the opinion of the Indy FAA office where all my applicants took check rides. I was able to teach 27 people through getting a pilots license in 1 year and have about 45 in the 4 years without a single failure. All passed on the first try.
Anyway. I could tell in the first 5 minutes of the first flight if they were going to be able to do it. Most white collar workers had a harder time then blue collar workers. I could teach a 15 year old kid twice as quickly as a 35 year old backhoe operator. I contribute this to video games and good hand eye coordination. Does this make them a better pilot? Not sure but they sure learn quick and retain well. The backhoe operator did learn the systems like hydraulics quicker. Tried to teach a few doctors and none made it past 10 lessons but one dentist was able to earn a license. All in all WOMEN made good pilots. Sorry guys. They pay attention to detail and are very precise in what they do.
My point is some people learn much quicker because of experience. I do not claim to be a heavy equipment operator but I have ran a drag line, dozer, many tractors, boats, airplanes, fork lifts, ect. I just have a knack for machinery like most on here. That does not mean everyone does but can complete the same task just taking 3-4 times as long.
