Not necessarily. They're contractually required to make X number of episodes, but there's no way to guarantee quality or ratings. If they make cuts in the staffing of budget for this show, the show quality will drop. Suppose they cut the VFX budget by 75%, for instance: the show will have horrible FX, but they can still meet their contractual requirements. Or they could cut actor salaries in future seasons (which maybe haven't been negotiated with the actors yet), causing key actors to quit, necessitating either re-casting (which is usually bad) or rewriting the story.
