Does it also imply that the set is dense?

What is a null set? Isn't it just a synonym for a set of measure 0?

And what is your question? Are you asking whether all sets of measure 0 are dense? The empty set would be a counterexample...

and so is the Cantor set I assume. I used to think they are both the same. They are indeed 2 different notions.

Now the Cantor set is uncountable. right?
