No because that's YJ-19, not 17 (which is much bigger than 533mm).

YJ-17 and 20 look kinda small, are they smaller than UVLS dimensions? What I mean is, are they utilizing the full dimensions of the UVLS?

YJ-17 and YJ-20 look sized right to me.

And yes, they would utilize the full dimensions of the UVLS. Remember the UVLS diameter is 0.85m, so the missile itself is a bit smaller than that to account for the missile canister wall. Then remember that YJ-20 (and also likely YJ-17) is cold launched, which shaves off a bit of the maximum canister 9m length to account for the cold launch mechanism.
