Eli5 why scientists say that no water could be found on other planets despite claiming that ice is present on certain places. Isn't ice and water are the same?

>why scientists say that no water could be found on other planets

They don’t. We have found water on many planets and other bodies within our own solar system (moons, asteroids, comets). It’s a lot more challenging to identify compounds which exist on planets outside of our solar system, but there are many such candidates which we think look like they may have water. 

Within our own solar system, water ice is pretty common in the bodies further away from the sun than us. Liquid water has been confirmed on Mars (not a lot of it at all, but it’s definitely there), beneath the water-ice crust of Saturn’s moon Enceladus, and is almost certainly beneath the water-ice crust of Jupiter’s moon Europa. Earth is the only place in the solar system we know to have large bodies of liquid water at the surface.
