It's the same database. After you select a month/year on the first page, you can scroll down to the folder icon which says "Movesets". At that point, you would scroll down to UU, where if you open it up, it'll have the statistics for each Pokemon, including abilities, items, natures/EV spreads, movesets, teammates, and sometimes checks/counters. If you see a number by a tier, such as UU-1630, that means that it only considers statistics at or above that level on the ladder. It helps to filter out the extraneous data.
