The Hau-oli City Lottery (which is what I assume you are referring to) offers you a daily chance at these prizes depending on the ID numbers of your Pokemon:
One Number: Moomoo Milk
Two Numbers: PP Up
Three Numbers: PP Max
Four Numbers: Rare Candy
Five Numbers: Master Ball

There's also another lottery in the game, the shops in your Festival Plaza. This lottery chooses the prizes randomly.
The different styles of Stores will give different top prizes and the higher the rank of the store, the more likely you get the higher prize

Prize #1- Master Ball
Prize #2- Rare Candy
