I have a question about table tennis. "There are 10 participants, but the number should be 16. What are the remaining six numbers for? " ?

This is based on the competition chart, because there are 10 contestants, and players in 16 positions have to participate to produce 8 champions, and then 4 of them will be produced, and then 2 will decide to win the championship and the third place. These ten people draw lots to decide these sixteen places, and those who have a bye will go directly to the next round.
