You're not really arguing with the original article, which is talking about perceived or perhaps realized luck. You're talking about the absolute or objective amount of luck which a person has. What the original article is really saying, isn't that you can train yourself to have the kind of luck that causes people to be born with a silver spoon in their mouths; rather, that you can become subjectively luckier by learning (i.e. a skill) to eliminate the mental barriers which cause you to underappreciate or underperceive the amount of absolute/objective luck which you have to work with.
