Explain this to me

This table contains stats for heroes' picks and bans.
Rank is used to sort heroes by winrate, taking number of their picks and bans into account. Higher rank means the hero is stronger. Rev-Rank (Reverse Rank) is used to show the least effective heroes with the most number of matches.
Balance metric estimates how balanced the meta is (0 to 100)

Median hero picks (mp): 9 - Median hero bans (mb): 1 - Matches: 1977

Remove low picks (0.9mp) Remove low bans (0.9mb)
