If one was to watch athletics on TV or at a stadium, they would soon see that not everyone is on the same level. Within each race, there will be some athletes who are at the front and there will be others who nowhere near the front.
In this instance, it is clear that some of the athletes are better than others. One is not being ‘politically incorrect’ by saying this; they are making a simple observation. Very few athletes break records or win medals and even if they do win a medal at one event, it doesn’t mean they will go on to win anymore.
