Are real estate agents/developers on the opposite spectrum of urban planners? would getting licensed increase my marketability if i also have a masters in urban planning? is it a wise investment? how different are the two professions/fields?

I'm considering becoming a licenses real estate agent for the purposes of increasing my knowledge in development and having the dexterity to 'ride the fence' in the urp profession. i'm interested in knowing whether you have any insight on this dual capability - how closely do the two coincide and/or overlap? if you have any experiences in doing or knowing someone who did it, or if you see any benefits, what would you recommend in pursuing this route?
