I do not know your option wins and loses? The article would apply to those that it would apply to. But it is a fact with most option players that approximately 90% are losers, this is no doubt referring to those that do not understand option trading especially new option traders, not professional option traders that have done there home work.
I think you are reading more into the article than is not there.
