What's dangerous is diarrhea, not watery poop. Diarrhea is when the feces, the solid part of the poop that looks like a little worm, are not solid and mix with the urine and ureates. Watery poop is something that happens occasionally due to diet or time of the day. As Harpmaker said, the first poop of the morning (bird people call it the 'morning bomb' -LOL) is always large and 'watery' because it has a lot of urine in it. When they eat a lot of certain fruits (like grapes, watermelon, etc), they would have a watery poop after but it goes back to normal immediately after. This is normal and nothing to worry about. Fruits are good for them and watery poop is absolutely normal and not dangerous at all when it's because of them.
Then you have polyuria which is kind of like chronic watery poop because it contains large amounts of urine but, once it dries, you would see the solid poop and a big stain of urine around it. It is also almost always accompanied by polydipsia which means an excessive thirst and consumption of large amounts of water. This is not good and a symptom of disease (could be liver, could be kidney, could be diabetes, could be thyroid, etc.) so an avian vet needs to see the bird and do several tests to figure out what is causing.
