That question is too simplistic to have much meaning. Can a console manufacturer make a big difference with regards to the success of a third-party game? Yes, of course. I can't imagine that anyone would argue differently. Is it always the case that the console manufacturer is a fault when a third-party game isn't successful? Of course not. Sometimes a product simply isn't appealing to consumers or the developers/publishers have themselves done a poor job.
You can't get a much more specific answer without a more specific question.
Now, if you want to compare console manufacturers, I think it's fair to say that Nintendo, from a historical perspective, hasn't been as good a business partner as Microsoft or Sony with regards to most third-party developers/publishers. Over time, that resulted in the audiences of certain types of games moving elsewhere. Of course, Nintendo has every right to run their business as they see fit and third-party companies have every right to do the same. Neither has a responsibility to the other beyond any contracts they may sign. However, any actions on that front can affect the future for many years, even many generations.
