His blog post acknowledges probability. Probability is the measure of likelihood, i.e. the chance of something happening. Luck is defined as a chance occurrence. If luck doesn't exist, there are no chance occurrences. If there are no chance occurrances, then probability is meaningless. If probability is meaningless, his blog post is ... crap?
