ETRTO is the only tire size standard that describes a real, measurable dimension, which is why it is the one worth trusting. Read 32-630 as “32 mm wide, on a 630 mm rim”. If the second number matches your rim, the tire fits.
Sidewall markings for this size are not consistent between brands. The same 32-630 tire is also printed as 27x1 1/4, 27x1.25, 700x32C — all of these describe the same rim fit.
