(meaning it can concentrate in one spot), then why do they say your air would be sucked out from your lungs in space?

1.) On Earth your body is being subjected to an atmospheric pressure of 14 Pounds Per Square Inch (PSI). So, to retain its shape, your body parts are designed to push back with a pressure of 14 PSI and thus stay the same shape, and not become all squashed up.
In space there is no atmospheric pressure. Pressure = Zero.
So, your own body would push everything inside you outward at 14 Pounds Per Square Inch the instant you entered a zero atmosphere environment. In essence, you would immediately burst open., and the various particles which flew out of you would drift about endlessly until attrracted to some larger object by that object's gravity force.

Your question implies that you assume there are places in space that are vacuum and places that aren't.
There is no total vacuum, even in space. Space is a very good vacuum compared to our experiences, but space is not empty. So particles are free to roam because there is no difference in "vacuum" in one area compared to another.
There are places where material gathers into clumps or clouds due to mutual gravity, and if a particle comes within the gravitational field of anything (cloud, asteroid, star) it will be "sucked" in by the gravity.
The air is sucked out of your lungs in space because space has a lower density (lower pressure) than your lungs.

The air pressure in your lungs would force all the air out into the vacuum of space.

Actually you would explode in space. On Earth, we are constantly under 1 atmosphere of pressure. We don't get squished because we have an internal pressure of 1 atmosphere inside out body pushing against the 1 atmosphere of pressure trying to squish us. Go to outspace and that 1 atmosphere of pressure ouside goes to zero and the 1 atmosphere of pressure inside out body now has only the skin to hold it back. I don't think the skin will be able to with stand the pressure and we will literally explode.

Because of the laws of thermodynamics - the pressure inside your lungs is larger than the pressure outside, and when you open your mouth, the pressures attempt to equalize - by reducing your lung pressure to pretty much zero and forcing out all the particles.

the reason matter isn't ditributed evenly throughout the universe is due to gravity, pockets of matter collecting to create gravity and form planets, stars, galaxies, etc. your lone body doesnt have enough gravity to hold on to the air in your lungs in zero pressure

it doesnt concentrate in one spot. without gravity to cluster particles equilibrium takes over and they even out. so if you were to open your mouth or anything the air would be sucked from your lunga because space is a vaccum and particles are constantly trying to reach equilibrium.

the air wouldn't be sucked out.
theres just no air (oxygen) to replace what you exhale
pressure is a little different out there and the closest thing that would happen to "sucking" would be cellular and vascular breakdown

The pressure. Read up on the Bernoulli Principle and his venturi tube effect.

The particles that are in space are already in the vaccuum. There's nowhere for them to be "sucked" to.
