not quite:
"take the win" - we say this in a situation where we may have suffered a loss BUT there has also been a win. And the advice is saying - "sure there has been a loss - but the win is real and better. Take the win and ignore the loss - move on!"
"Take it as a win" - this means that you interpret a situation as a win. even it wasn't really a win or maybe the win was a small victory.
