Nobody said it was a win for philosophers. It says it's a win for a philosopher (singular), and it is because he won the bet and therefore won a case of wine.
It is a sort of win for the kind of philosophy this philosopher practices. He thinks that there is more going on in consciousness than just neurons firing.
It doesn't really prove anything, of course. I actually don't think much of Chalmers' work. But it's very remarkable that the bet expired just as machines are coming tantalizingly close to being consciousness without qualia.
It could be double speak, but the obvious thing you understand from this formulation it that he won because he is a philosopher. Not that he won, and by the way he is a philosopher.
