If I understood this correctly, they analyzed incredibly blurry images and concluded that there are clouds of gas around galaxies, then they extrapolated the found gas up to all or almost all galaxies and concluded that it can fulfill the calculated expectations.

What I understood is kind of the opposite–they already knew there were hidrogene clouds around galaxies but analyzed some almost imperceptibly blurry images and found they were bigger than currently thought. They're blurry because they were taken in some wavelength not observable until now that is scattered by the ionized gas.
