[DC] How can Batman possibly be an urban legend, doesn’t he do justice league press conference?

Generally, the conceit is that he started off as an urban legend before moving into the limelight.

He isn't one anymore in mainstream continuity, but he *was* at the start of his career, and given that a lot of adaptations take place fairly early in batmaning, that characterisation remains common.
