The player in the white dribbles the ball, while the player in the orange tries to stop him.
The player in white and the player in orange are participating in a pick-up game of basketball at the gym.
Basketball can also be played in an organized setting, not only in a pick-up variety.
We have no idea if they are in a pick-up game at the gym, he could be playing any type of game and he could be playing anywhere.
Just because the player in the white dribbles the ball, while the player in the orange tries to stop him does not mean they are participating in a pick-up game of basketball at the gym.
