Bracket shows the most probable team in each Play-In + WR1 based on the sim's most probable outcome.
The percentage indicates the probability they land in that seeding position, which may differ from their overall probability of reaching that round (e.g. a team could have a 40% chance to reach WR1 but be the underdog in all their WR1 matchups, resulting in a low probability of actually being the favorite in that slot).
