If i have a bottle full of water (there's no air in the bottle) with a straw in it and the bottle is sealed completely without any opening except the straw, will i be able to suck water out of the the bottle with the straw?
Yes, but only because the water has a vapour pressure greater than zero. If the liquid in the bottle was completely non-volatile then you would not be able to suck it out.
Suppose you reduce the pressure outside the bottle to zero. The water will start to vaporise and form bubbles of vapour that have a pressure greater than zero. These bubbles will expand and push out the water.
With a non-volatile liquid no bubbles of vapour will form and the pressure inside the bottle will be the same as the pressure outside (both zero). That means the liquid will not be expelled from the bottle.
I don't quite see the problem: you can alternate sucking out some water and letting air enter the bottle through the straw. If necessary, you can change the orientation of the bottle at some point to use gravity.
