I can calculate the probability of a single event happening, but I can't predict the results of a single event. This becomes quite the real problem when devices only have but a handful of electrons to do their work with.
Scientists have been doing experiments with single electrons and photons for a long time now. The results are highly predictable. They do use probability, but that is also a branch of mathematics, and I don’t know of any competent scientist or mathematician who would equate it with the supernatural or magic.
