Representation

The clip demonstrates 3 groups, including men, people of white background and prejudgment from appearance.

Men - A dominant portrayal, seeing that women do not usually play sports, especially basketball. Additionally, tennis, volleyball or badminton instead.  

White background - An alternative portrayal as it challenges the stereotype thought to usually only see people of a black background to play basketball.

Prejudgment from appearance- One of the guys point out that them wearing a jersey makes them good at basketball by default, however later on we see that this is obviously not the case.

A blatant stereotype is that people of a white background are not very good at basketball, or mediocre at best, and I think this strongly comes from institutions such as the NBA, where the majority of professional players are black.
