It is exactly like that, but it is not just about stopping hunger and thirst that one gets sustenance. Rather, it is about avoiding evil and performing as many good deeds as possible to please Allah, including helping the poor, breaking the fast, and providing food to someone's house. Apart from all these, keeping oneself busy in the worship of Allah Almighty, etc., is part of fasting. And the greatest joy is that its reward is due to Allah Himself. Because in Ramadan, the devils are locked up. And He is the Lord of countless rewards and rewards.
