Five men playing a competitive game of basketball with the man in the black tank top and black shorts in possession of the ball.
The 6 guys played a competitive game of basket ball where the teams were set as Three versus Three
You can't imply that there were 6 players rather than 5. Since the words basket and ball are separate we can't assume they were playing the same sport. We can assume that there are teams but not that the teams were Three verses Three.
