Is John Three Speaking About Baptism When It Says That You Must Be Born Again?

i want to first address the question of, is john three speaking about baptism when it speaks about one who needs to be born of water and the spirit?

And in order to enter into the kingdom of god, jesus explains that one must be born again. He explains what it means to be born again but then he says that you must be born ofWater and the spirit. I don't think the verse helps luther as much as they think that it does, because it says more than they are
