I really don't find DIY requires more skill than the usual house work.
Putting up a picture: nail a hook to the wall (you just need to get used to the hammer, really, and be able to hold the nail in place - there are tricks for that.)
Painting walls: choose the paint, protect floors and anything that is not to be painted, paint, let it dry.
Laundry: you must understand that you should separate colours and types of clothes, choose the temperature, then hand so that the clothes dry faster and without markings.
Ironing: shirts and trousers require care and attention. We must select the best temperature for the clothes, the pressure to apply, how fast to do it, how much steam to apply, and so on.
Cooking: unless you just heat up ready meals, it involves a range of skills that require some learning and lots of practice.
Cleaning: you must choose the best products, understand what they do (no, bleach won't get rid of grease or limescale), and do in the right order.
I've installed a kitchen at home and, step by step, it doesn't require fantastic skills. It's pretty basic. As is putting laminate flooring. And exH a school leaver but he figured out how to do basic plumbing.
It's just something we rarely do and we need to be taught the basics and practice a bit. We just get to practice day to day house work a lot. :)
