Yes. Canon is usually defined by what the main publication method of a series is. In our case, it's the manga. Everything that is not the manga, but uses characters or other things from the manga, is not entirely canon. Of course there are things that are semi-canon, like the novels, but there are also things that are as far from canon as it gets, for example the games or the TCG.
