LOL obviously there is a very close relationship between rank and skill, people just say otherwise because they mad cus bad. No but seriously, if you have 2 players of different ranks, much more commonly the higher ranked player will be "better" (in quotation marks because there are many different aspects that can make a player good, so better means in the eyes of the objective referee). People who are lower ranked and better that a person who is not too close to their rank, are the outliers.
