Nope, MAU = How many players played your game in a month, so even if a player joined 50 times and played for 80 hours this month, it’s still 1 player only.
Even if someone only played for 3 minutes and left forever, it’s still 1 player.
MAU = Monthly Active Users
(but in reality they don’t have to be active, they just gotta join for a few minutes)
