No, it isn't. But your understanding that it doesn't work is correct.
Still, I'd like to know - rather than by negative example - in what arena do you see it as possible for every participant to win?
it will never be possible for everyone to win. What bitcoins could theoretically do is to take away banks power, so that 99% of people would not be losing against banks, freedom from bank control, but at the same time, banks have their purpose and they will always exist, this is what history tells us and to believe otherwise is to believe in some kind of utopia
bitcoins have their purpose - money laundering and privacy, faster transactions and low fees, freedom from government control (although government is supposed to work for people, so that's another issue)
not losing is not the same as winning
