If a particle of dark matter passes a star, they'll deflect each other

The generic term for this is "dynamical friction."
If dark matter particles are light, oh, lighter than Jupiter, this
start/darkmatter gas is going to end up giving the dark matter
particles speeds much greater than the stars. This may take awhile,
You might find it enlightening to calculate just how long the
timescale is.
