Wasn't the All Blue in the Grand Line?

Hi. So I've finished watching the anime and haven't read the manga (yet) but it's been a hot minute since the starting few episodes. As far as I recall, the crew set out for the Grand Line for their own dreams, including Sanji who wanted to find the All Blue. But right now, they're in the New World right? Isn't that past the Grand Line? So did they miss it the first time or... Am I getting the geography of the show wrong? I know there's this theory that they would have to go around the globe AGAIN after finding Laugh Tale, just like Roger did.. (unless I'm getting this wrong?) but I think Luffy's dream would most probably come true after they have all reached their goals right? Or would it be the "actual dream" Luffy told everyone about that goes beyond just becoming the King of the Pirates?
