I don't think that was implied, but rather the sun does, what the sun does and we do, what we do. If we do not have free will, but every action, every thought is a determined reaction of the state of things, than we would also be "trapped". But we do not (normally) perceive it as such. We experience our lives and we live it. We act. Even though our actions might come from a deep automatism. For the sun it might be the same, just on a whole different level.
