I'd say knowledge is not the only thing you need. It's one thing to know, and entirely another thing to be able to recall and apply that knowledge when it matters.
The application of knowledge gets trickier because there is almost always no "right answer". Everything is a decision, a choice. There may even be conflicting but contextually correct ways to process the same decision - i.e. Early bird gets the worm vs second mouse gets the cheese.
