Not really. More important things to learn are Pokemon categories and types. Types are literally the most important thing about competitive battles. If you don't have a nearly flawless grasp on type match-ups, you will lose with even the best teams. By battle categories, I mean the role each Pokemon will play on your team. There are Walls, which are meant to be durable Pokemon that can outlast your opponent. These Pokemon usually have high defensive stats but low attacking stats. There are Sweepers, which are meant to be your power houses. They usually have high offensive and speed stats but lower defensive stats. There are a lot more, but in the beginning you want to just focus on these two. Who's good at attacking and who's good at defending. That balance can be key.

Hmm, walls and sweepers? I usually only think in terms of good attack, as a dead enemy doesn't deal damage anymore. Maybe Pokemon is more complex.

As I don't want (yet) look at the Pokemon and their base stats in detail (first getting basic details together), I take a look on the type table. Seems like steel might be a good type for a defensive Pokemon, a wall. Is that right?
