Water always finds its level right? Like, it will never conform to a ball we've tested this. But bubbles are always spheres?
Yes, you can consider it as always finding its level.
The question then becomes, what is level?
Most people think of it as a flat surface, but that isn't the case. In reality it is based upon a multitude of factors, but the simple way to consider it is if you were a point on the surface of this water, if it wasn't level then you can lose energy by travelling in some direction along the surface; if it was level then you keep the same energy by moving along the surface.
On the small scale, such as droplets, surface tension dominates and forces it into a spherical shape. This also dominates near the edges of water, where preferable interactions with a surface such as most glass cause the water to try and stick to it and creep up it a bit. With a hydrophobic surface the opposite happens and it curves down at the edge, or just sits as beads on the surface.
At the large scale, ignoring the edges, gravity and the apparent centrifugal force dominate, and thus for Earth, water adopts a roughly spherical shape.
So yes, it can conform to a ball. The reason it typically doesn't is because you are likely testing within Earth's roche limit, and aren't testing it in free fall.
This means the gravitational attraction to Earth can rip it off the surface of the ball.
But all that shows is that Earth can't be a sphere being held "stationary" above a much larger surface with significantly greater attraction.
A similar experiment would be holding a flat surface perpendicular to Earth and noting the water falls off it. It doesn't show water can't stay on a flat surface, just not one in that arrangement.
