Not necessarily, because of quantum uncertainty and indeterminism -- and yes, they can affect macroscopic systems.
The deeper point is, whilst there is a subjective ignorance-based kind of probability, that does not by itself mean there is not an objective, in-the-territory kind of 0<p<1 probability. The latter would be down to how the universe works, and you can't tell how the universe works by making conceptual, philosophical-style arguments.
So the kind of probability that is in the mind is in the mind, and the other kind is a separate issue. (Of course, the existence of objective probability doesn't follow from the existence of subjective probability any more than its non existence does).
