Why? Because hydrogen chloride is very soluble in solution, and in solution undergoes almost complete protonolysis.
Explanation:
...hydrogen chloride undergoes the protonolysis reaction...
...and this equilibrium lies strongly to the right as we face the page.
And given a starting mass of hydrogen chloride gas, we have an equivalent quantity of hydronium and chloride ions in solution, right up to the maximum concentration of hydrochloric acid, approx.
On the other hand, for weaker acids, say hydrogen fluoride, the equilibrium would lie somewhat to the left and
