'hungrig' and 'durstig' both describe a physical need. 'hungrig' fits when you want or need to eat something. 'durstig' fits when you want or need to drink something. Learners may confuse the words because both often occur after sports, work, or a long break. Figuratively, both can express a strong desire, but in everyday life the physical difference is most important: 'hungrig' for food, 'durstig' for drink.
