Is the size of the Universe defined by how far light has traveled since the big bang?

You have been told in basically every one of your questions to stop asking this kind of things.

Anyway, saying that is like saying a completely dark room is not a part of the universe.

What do you mean by "size"? What we can see is defined by how far light has travelled since the surface of last scattering.
