It usually means you can't use it in any render that you get paid for doing.

That's what it should mean, but some people use it when they mean it is not for redistribution as a 3D model and/or not to be used in the creation of new 3d content for distribution. As CHMedia says, if it's not clear from the read-me or equivalent then ask the maker - but if you can't get clarification you probably have to take it at face value, meaning no commercial use of renders.
