So that means the flash IS determining the exposure because it is brighter than the light in the room?

yes, it sure looks like your splashing water glass has the camera flash as the main light source.

With an external flash, you could control direction of light and intensity better.

The camera flash is mostly used as "emergency flash" when no other light is available, or as fill in flash, i.e. when the ambient light is strong enough to give you a picture with your camera settings, e.g. 1/100 f8, but your object has the light in the back, and is thus dark, so you can brighten up the face with the flash (the auto modes may do it sort of okish). But if the sun is strong outside, and the subject far, the flash won't be strong enough. It's all about the balance between flash and ambient light.  Indoors it's not unusually that the flash will easily be the dominant light source.
