wrong. it means exactly this.
i assume you were already wrong in your statement: you said „infinity of universeS“ the „s“ at the end implies you talk about multiverse theory and not the infinity of the univese (without s). because when you take bubble theory (everett graham wheeler model, see https://en.m.wikipedia.org/wiki/Many...interpretation) it is exactly the case that everything that CAN happen, in some universe WILL happen. this is meant for every single combination of atoms. which ofc let also exist a warcraft universe and everything you can imagine and that fullfills the rules of our known universe. in example in the warcraft universe magic can exist if it falls under the rules of psychics and is just simply somethimg we understand not yet. as long as it is possible by atomar combinations it can exist there. in short: everything is possible.
when you take away the s, THEN you will be right. just because our (one and only) universe is infinite, doesnt mean somewhere out there is i.e. draenor. the chance are not that high that this will happen.
