Capitalism isn’t airtight against all cases of win-lose or lose-lose in any realistic formulation, but there are many, many real specific cases in which it is win-win.
Just because it contains specific win-win cases doesn’t mean it’s win-win in the grand scheme. You can get win-win scenarios in a strict command-and-control economy, even in cases where capitalism performs poorly (it provides better footing against tragedies of the commons, for one,) but that doesn’t make it a particularly viable economic model overall.
