This can't be true, unless the defn is chosen to make it vacuously true.

For example, even classical 3-body Newtonian gravitation is chaotic in such a way that the future cannot be predicted.  One can set up initial conditions on a 3-body gravitational system in such a way that the ensuing chaos can encode *all of the infinite number of bits* of any given transcendental number, whether or not such number has a finite Turing Machine description (a la Chaitin).

If such a sequence of bits doesn't conform to most peoples' definition of a "random" number, then I don't know what will.
