Basically, yes -- but the full answer is not so simple.
Gravity does "attach" oxygen atoms to the Earth, but it's not quite that simple, since atoms and molecules don't stand still -- they actually move pretty fast. Fortunately, very few of them move fast enough to reach "escape velocity" -- the speed required to break free of the Earth's gravity pull.
a very tiny amount of the Earth's atmosphere does escape into the vacuum of space. The rate is very slow -- if it has been constant for the estimated 4.5 billion years the Earth has been around, a sphere covering the entire Earth about 1 meter thick would have escaped by now (in other words, not very much at all).

Why is because.. vacuum is another kind of environment with no air, no ... insulated box with holes for the air to escape
not really becasue of gravity

just like gravity keeps our feet on the ground it keeps the our atmosphere in place.

No!!, its because of us, the air is sucked down by all living things plants inclded generating a vacumm effect stronger than that in space and thus holding the air down, so do your part n keep-breathin...
