So Mary isn’t part of ‘all’? Not a human? The woman who called God her Savior? Savior from what exactly?
John the Baptist was also born without original sin.
In a word, “no”. Mary isn’t part of the “all” you mention, (all have sinned), just like babies and mentally retarded children/adults aren’t.
Ever hear of hyperbole? It’s used a lot in the Bible.
