No, it really isn’t.
They are metaphorically identical, which is why Nicodemus asked Jesus if he had to crawl back into his own mother’s womb to be reborn.
Yes, the “begotten from above” is literal, but it is functionally the same as being “born-again”.
Being “born-again” is the result of the hearing of faith, it does not happen at baptism, for example.
That is a quite common misconception. (no pun intended).
