Ionic character increases with the difference in electronegativity between the two atoms forming the bond. H-H has no difference (being the same element), C-H has a small difference, H-Cl has a larger difference (chlorine being much more electronegative than hydrogen), and O-H has a significant difference but less than H-Cl, making O-H more polar covalent compared to the ionic character of H-Cl.
