But all statistical distributions follow some sort of probabilistic curve roughly the shape of the Gaussian curve.


No. no. no. A 'bath tub' curve is a common statistical distribution that is not roughly a Gaussian curve, nor is a bimodal distribution. Normal distributions are common because of certain mathematical properties.

What I mean is:

Ensembles of particles follow statistical distributions of the family of the Maxwell-Boltzmann function.

Okay?

Are we done with semantics?

The answer again is no, no, no. Thermally released electrons in a conductor do not follow this notion of yours.

What you are saying is true unless quantum effects are the primary effect.

Let me quote the wikipedia
In statistical mechanics, Maxwell–Boltzmann statistics describes the statistical distribution of material particles over various energy states in thermal equilibrium, when the temperature is high enough and density is low enough to render quantum effects negligible.


So a piece of metal such as a car body has free electrons which are due to thermal excitations, then these electrons do not behave according to this law.

Really? Hmmm. Maybe I am missing something. What do they do then?

I thought that if there are free electrons due to thermal excitation, they are randomly excited, and if you look at the energy states of electrons they are bell-curve distributed (more or less).

Electrical current (e.g. the speed of movement of individual electrons) I'm fairly sure do follow a bell(ish) distribution.
