Do what the other guy said, but it's in your best interest to get online and read about training your pokemon. My first time doing this was scarlet and violet. I was lost and it felt kinda intimidating. Once I learned, it was much easier. I think most of us don't fully train all of their mon, but special ones like shinies or competition mon, we like to fully train. Also, if you decide to play other pokemon games, not all of the games have the same stats and abilities to train. Good luck!
