If anything of Quantum Physical Theory is true, then it is possible that it is not a number itself that inherently has any power, but rather the observer's belief in such a thing where a number's power lies.

In other words, if it is believed that a number is lucky, then that number may be imbued with luck. To go along with that, a belief that there is no such thing as luck may well be the reason a person is not subject to luck.

That's all just simplified for the sake of brevity, of course.
