Its just an expression.
Yes, they are excellent.
In our example, saying that a team won because they “wanted it more” implicitly raises an expectation that a description will follow of how that team practiced harder, were resilient, and tried and made exceptional plays. If so, that ought to be said and grounded in facts in order to advance the reader's understanding of what happened and of how the world works. Subtly, the reader is being told that winning at sports and in life requires not just desire but also determined effort and sacrifice toward a goal.
Or maybe a team won because of being lucky or unusually talented, which offers different and harder lessons about how success is sometimes not earned or that wanting something more and working harder does not always lead to success. If you are beaten by a home run from a dissolute Babe Ruth nursing a hangover there is a story to tell even as greater effort and desire can be said to have deserved a better result -- but maybe not that year.
I mean this not as a criticism but as an explanation of my comment. On reflection, you may agree with me. Woe if you do because you will find that the scrutiny you apply to what you write and read becomes more exacting. Do that as a matter of habit and you will find in time that attention to clarity and logic in expression fosters a better understanding of what you read and greater comprehension of ideas, facts, and events.
