Could a terrestrial planet have water for a core?
$begingroup$
There’s a planet called eaglypt whose surface is 100% barren desert. However, there is a twist: the planet’s core consists of liquid water, and there are a few places where this water seeps through the cracks and reaches the surface, where it creates fertile oases where civilizations can spring up, using the oases for irrigation. Is this realistic for a planet to exist like this or would it take serious artistic license for it to exist?

Water cannot remain fluid at the pressures of a terrestrial planet's core. However, it doesn't need to for your setting to be viable. The planet's crust could simply possess large, deep aquifers that provide water to oases. Some good examples of large aquifers beneath a desert are Australia's Great Artesian Basin, and the Nubian Sandstone Aquifer System.

For water to be at the core of the planet, it must mean that there are no other elements or components which are denser than water.
Now, water is pretty dense, but nowhere dense as most of the metals or oxides.
It can happen that only light elements are collected by gravity, but such a planet could not host life as we know it: no magnetic field to shield stellar wind, just to cite one big difference.
