Electrons in an atom don't have a [specific] location. It's not a concept that exists for them. So, yes, it's a probability.
Despite the common image, electrons don't orbit the nucleus like planets around the sun. They sort of exist around the entire thing in all locations at the same time (in 3D, not in a ring, but a shell).
