You have independent knowledge of psychology, evolution, game theory, etc, (and hypotheses under which they matter, in which the being with vast power evolved naturally and then discovered that physics in its universe allowed unbounded acquisition of free energy to generate apparent worlds like ours, etc) it would be an extraordinary coincidence if those probabilities were really exactly equal (unless one were engaged in motivated cognition to avoid the issue by any means whatsoever; this not necessary, as no one can force you to act like you have an unbounded utility function if you don't have one).
