Maybe I was unclear about what I mean with "most of". I meant that in a qualitative way. I would say that the "99% of the time" implies that the quantity of issues comes from engineering problems of all kinds, and I would agree with you that many educational systems tend to forget to teach people simple craft while focusing on theory. On the other hand, I would say the 1% is more damaging in nature. That's why I said 'a lot of', because these things will really hurt in the long term, rather than the ton of small bugs that are caused by bad engineering.
