Casinos absolutely do. There's a litany of stories about casinos enabling gambling addicts by offering them free rooms, drinks, food, flights, whatever it takes, to keep them coming back because they know these people have a psychological condition which they can profit off of. It's exploitation.
Active vs passive is where I draw the line. Passively being enticing is not the same as actively coercing someone to do something. If passively enticing is considered preying, then the number of things in the world that "prey upon" people goes up by orders of magnitude. Fast food restaurants are now preying upon people by posting delicious advertising. It becomes a meaningless term.
