Zero-g is an absence of weight or weightless, not the absence of gravity. The 'g' (lower case letter of G) from zero-g means g-force, is a measurement of accelerations that indirectly produce weight, can be implemented as a "weight per unit mass."
You can feel the sensation of being zero-g or weightless while doing sky diving from very high altitude without looking at the ground.
So do those astronauts in the outer space.
Astronauts in outer space above the Earth's atmosphere are actually not floating, but falling curving the Earth as the Earth curving and moving away from them. So they keep falling
The Earth does curve and move as the part of its orbital to itself and towards the sun.
