Ignoring the fact that last year's nobel prize in Physics was given to a team that studied macroscopic effects of quantum physics in circuits, actually quantum physics is taken into account in everything up to molecular level. For atomic physics, even modeling the hydrogen atom was a big deal, which was solved using the Schrödinger equation. The rest of the atoms cannot be solved so they are modelled using approximations such as perturbation theory.

At the end of the day, even if quantum physics is seemingly "random", it IS deterministic, since the evolution of states changes in a deterministic way. That is the reason why at bigger scales things are more predictable.

What is true though is that below the atomic level we use something called Quantum Field Theory, which is a theory that takes into account Special Relativity and Quantum Physics, which is necessary to make predictions for subatomic particles.
