Steam Cloud is implemented on a game by game basis. Even if a game uses Steamworks, it doesn't necessarily make use of Steam Cloud, especially if it was released before Steam Cloud was made available to developers. It would've been up to the developer to patch support in. All Valve games have Steam Cloud support, for instance.
I also wanna say I had to enable Steam Cloud myself way back when it first went live, but that option doesn't seem to exist anymore, so either I'm remembering wrong or it's since been made an automatic feature.
