There's always a difference in performance when there is a difference in motivation. I'm sure they will all try to win still, but the person who is in with a shot to win the tournament is likely to fight a little harder, pick a slightly safer strategy, make safer choices, pick safer fights etc, whilst the player who can't win the tournament might do some yolo moves and such since it doesn't really matter for him. Maybe he prefers to put on a good show for the viewers and do a fun strategy since he can't win anymore?
Even if it's not the intention to do so, it's just how it is, it's the mental aspect of it all. People are different though, so it might be enough for some, not for others.
