Teaching yourself is hard; if it wasn't, we wouldn't have schools or tutors, or at least as many of them. Most people aren't autodidacts. One's IQ and Conscientiousness probably dominate one's ability to do it, but even so, things like genuine interest play a big part too. Try teaching yourself a subject outside of tech sometime and see how far you go without that much interest. Then there's a time and energy component. A lot of people wake up and go to work, then come home worn out, or at least at less energy than earlier in the day, and they probably have other things to do for their remaining 1/3 of the day besides devote it to self-study. At least for programming, self-learning most things is super cheap, so the cost barrier isn't as big, but again, self-learning is hard, which is why so many pricey bootcamps have popped up.
