Yes. Concepts can stop making sense in situations that take them apart. For example, it makes sense to ask whether an apple is a fruit, but it doesn't make sense to ask whether an atom inside the apple is a fruit.
Even if you'd take just one electron, its cloud is infinite. Like, really, when people talk about things like shape of the cloud, what they mean is the density of the cloud, or the shape that you get when you only take the region where the density exceeds some arbitrary level.
So, from this perspective, as long as at least one electron exists in the universe, there is no empty place in the universe. Because, with infinitesimal probability, the electron could be anywhere.
Obviously, this is NOT what we mean by emptiness in everyday life.
