Are all liquids incompressible and all gasses compressable?

I've always heard about water specifically being incompressible, eg water hammer. Are all liquids incompressible or is there something specific about water? Are there any compressible liquids? Or is it that liquid is an state of matter that is incompressible and if it is compressible then it's a gas? I could imagine there is a point that you can't compress a gas any further, does that correspond with a phase change to liquid?

Edit: thank you all for the wonderful answers and input.  Nothing is ever cut and dry (no pun intended) :)

Liquids are ‘incompressible’ in that they are only slightly compressible.

If we set ‘z’=1 where a fluid density doubles for a doubling of absolute pressure at constant temperature, liquids have a ‘z’ between about 0.001 and 0.05.

Gasses/vapors typically range from 0.4-1.6.

Z is compressibility.
