Short answer yes. Hamsters may suffer from a condition called “wet tail” which usually manifest itself with watery stools. Because their body doesn't absorb water properly they tend to drink a lot. This condition is usually fatal if not treated ASAP. Of course there could be many more reasons for a hamster to suddenly drink more (like change of food or kidney problems) but “wet tail” is the most common condition to cause this symptom. I would advice to take him to the vet, the sooner the better. Food luck!
