A paintbrush is not a machine in the sense that the word "machine" is used in elementary physics. Machines are used to do work, usually by providing leverage in some way.
In that way, Atwood's machine, a collection of ropes and pulleys, is a machine, but the gasoline engine is not.
This is merely an issue of terminology and classification and has historical roots. It is not a statement of a basic law of science.
