The safest analogy I can think of are the rules of team sports.
The rules specify how the game should be played and is equivalent to the schematic. A video of a game is equivalent to a layout.
If you are trying to decide if a game has been played correctly, you can't do it from the video alone - though over extended time you might be able to have a good insight (reverse engineer rules/schematic).
Likewise, if you only read the rules, you would have difficulty envisaging how the game is played in real life and you would be thrashed.
It is extremely difficult to find problems without the rules (schematic), it is very difficult to play without the video (layout).
Yes, there are holes in the analogy, I was going to do plumbing but there were more holes in that analogy.
Any attempt to discover how a circuit works involves using a schematic in one form or another. If you are not interested in how it works you can treat it like lego, but if you want to fault find or modify it, you need to know about how it works.
