Script Writing - Is There a Difference Between Notes and Notes?

When i'm talking about notes in the context of writing a script, what i mean is really, here are all the factual building blocks out of which a piece of writing can be constructed on top of. And lots of them end up being just a single sentence or two. But that's just through pure happensance. Your every note that you create has the possibility to be more but it's just, yes, this note just ends up being this one thing.
