Exactly it is like the video games but worse because the anime showed that it is not shackled to the games such as Esperon Versus Pikachu. Ash never got his real potential to be someone other than mostly like all the pokemon trainers. He didn't deserve the win. This win was so like many other anime battles- the dust made the win. Opponents hit and there is no sense to decide who wins. The dust won this pokemon championship.
You aren't really explaining yourself much here. How is it dumb? They are both attacking fighting at their limit. So yeah they are going to do everything they can to win.
This is not video games. The game mechanic has never had an impact on the anime,
They aren't doing anything clever in tactics nor doing something where the viewer can understand how the resolution of the conflict should work.
No its not like that with every anime aimed at kids. Avator- Last Airbender is much more interesting. Children can absolutely handle battles with some sort of tactics. No advanced tactics are possible in the anime.
