DIY YouTubers read books, experiment, learn from others, and do extra-research. Most of the trades people are not doing any of that stuff. Almost all residential trades are poorly trained: many go to some trade school, get a job at a local contractor who doesn't want to further train. Unions are good at training; however, they want people to spend four years as an apprentice.

the DIY youtubers also know they will get a thorough drubbing in the comment section and may even lose subscribers if they do it to a poor level. the incentives for shortcuts on a job site by a worker are to get the job done(good enough for a layperson) and leave.

As soon as you learn enough you can start your own business and become the Boss client sees only twice :)

That’s kind of the problem, you don’t need to learn much at all/anything to do this right now. Because the bosses of the world aren’t enforcing any standards in terms of craftsmanship or quality of work. They pretty much just show up to see how much of a mess has been made and how quickly they can patch it up in order to ask for final payment or whatever is needed for completion
