In the natural world the answer is definitely yes. Naturally occurring metals where the only things that really conducted. But with modern civilization we are extracting the metals out of the minerals. But still there are more non conductors.
Valence electrons only are able to cross the energy gap in semiconductors since it is greater than that of conductors. That is why semiconductors have fewer free electrons than conductors.
Generally, non metals are non conductors (with exceptions such as graphite, fullerene etc)
metal
There are plenty of non conductors in the world. The most common is probably plastic or rubber. Glass is also non conductive. Hope this helps!

One fewer than the base for the number system.
strong
non metals are gases and are poor conductors at room temperature
