Hello! Question,
Would the water pressure in different oceans on different planets be the same as the oceans here on earth? If yes, please explain and if no please explain as well.
Thank you!

I think the simplest explanation is an equation:
P=D*g*h
P is pressure (or pressure head when dealing with more than just static pressure)
D is density of the fluid (usually represented by the Greek letter rho, but I don’t have that on my keyboard)
g is acceleration due to gravity (~10 m/s^(2) on Earth)
h is height of the fluid column above you (be that air or water or oil) aka depth below the surface
So, gravity has an effect. Different planets with different gravities will exert a different pressure under the same depth of water. A different fluid will exert a different pressure than water because of differing densities (easily seen with air vs water. You live under a roughly 100 km tall column of air without noticing it, but 2 metres under water is very noticeable).
