ANSWER;
Classical Thermodynamics studies the relationships between the State functionsof the system: i.e. Pressure, Temperature, Volume, Energy, Entropy etc. In classical thermodynamics we pretend that we don’t know anything about the microscopic constituents (atoms) of our thermodynamics system. We do not talk about concepts like microstates, or ensemble averages, since such concepts require a more fine-grained perspective of the universe.
Statistical Thermodynamics studies how the state functions can be statistically related to the individual microscopic components of the systems. These microscopic components can either be described classically, or quantum mechanically, depending on what limit we are in. Ultimately, almost all of statistical thermodynamics is derived by summing over the microscopic properties to derive equations for the macroscopic state functions!
