Props means to give proper recognition to . I don't know about Ozman, but it could be that there is a person with a name like "Ozzie" and "the Ozman" is a slangy nickname. My last name is Coddington. Someone might call me "the Coddman". Always with "the". It connots admiration.

In this case, “props” means “respect”. It is slang, a compliment.
