Luffy only beat Cracker with Nami's help, as for Katakuri he literally stabbed himself to give Luffy a fighting chance in otherwise curb stomp battle.

If Hawkins can injure Zoro to extent he needs medical attenion, I don't think Zoro can put dent in Jack without Luffy, Law, Sanji (yes even him) and the others help.

Jack literally fought a army of Sulongs, Fujitora, Sengoku and surived getting bitch slapped by a Kajiu sized Elphant. I like Zoro but Jack would grind him into a paste.
