What percentage of Clash Royale players have 5000 trophies?
It was nearly impossible to win against a higher levelled opponent if you were not twice as good as them. Chances are, 99% of you are not professional players and are somewhere below the ranges of 5000-6500 trophies (where 90% of the player base is). This is the base of CR's (for a lack of a better word) genius model.
