Why doesn't dark matter reside in gas clouds?

Why is it that dark matter does not inhabit gas clouds, I would have thought that thees gas clouds will some day become a galaxy, so why no Dark Matter?

I am not sure I understand the premise of your question. Do you have a reference?

This Wiki article tries to explain Dark Galaxies, but as yet there is no proof of the existence of thees galaxies, If indeed thees gas clouds contain Dark Matter then one can see how galaxies form, but if there is none then that makes matters complicated.

From the article.
A dark galaxy is a hypothesized galaxy with no, or very few, stars. They received their name because they have no visible stars,[1] but may be detectable if they contain significant amounts of gas. Astronomers have long theorized the existence of dark galaxies, but there are no confirmed examples to date.[2] Dark galaxies are distinct from intergalactic gas clouds caused by galactic tidal interactions, since these gas clouds do not contain dark matter, so they do not technically qualify as galaxies. Distinguishing between intergalactic gas clouds and galaxies is difficult; most candidate dark galaxies turn out to be tidal gas clouds.[3] The best candidate dark galaxies to date include HI1225+01,[4] AGC229385,[5] and numerous gas clouds detected in studies of quasars.

As stated, the gas clouds are the result of tidal interactions between galaxies ripping the gas out of the dark matter halos. Hence, no dark matter.
