why are the accretion disks for black holes always depicted as a disk? would the accretion of matter not occur as a sphere around the black hole?

As it collapses under gravity the angular momentum is conserved - this means a large thing spinning slowly becoming a smaller thing must spin more quickly. As it spins more quickly it starts to flatten out into a disk - because stuff at the edges is pushed out.

a ball spinning fast enough turns into a disk

So what determines the orientation of the disc?

it is important to realize that the net angular momentum of any random gas cloud in the universe is not zero. The entire solar system very obviously has a huge angular momentum.

Born with spin.
Die with spin...

HOLY SHIT I JUST REALISED THE SHAPE OF THE UNIVERSE.
