This can be summarized as, "I can tell you what it is, but I cannot understand it for you".

In such cases I've invariably found that the failure is on part of the person who is telling the thing - they are simply failing to communicate effectively.

They are not emphasizing the important points, they are not working backwards from the result that they want to achieve and merely listing steps to get to the result, they don't empathize with the audience so they cannot customize their narrative in a way that resonates with the audience.

This is exactly why in your 16 or more years of education with dozens of teachers, you can only name a handful that actually were good teachers.
