That's an example of an argument that assumes what it should be proving, the original meaning of the expression "begging the question." The question at the center of free will is whether there are any deliberate, choice-driven elements in human behavior that also and coincidentally defy advance prediction. Your argument is that the presence of unpredictable elements proves the existence of unpredictable elements. It's also a tautology. And finally, unpredictability doesn't prove free will, it only proves the existence of unpredictability. Free will would be a deliberate steering of the process toward some goal, something that true randomness contradicts.
