ok. so this ayat tells us that Allah sent ‘prophets’ who were ‘mubashir’ [bearers] of glad tidings and ‘Nazir’ [warners]. and scripture came with them.
they (prophets) bore scriptures and were judge for the disputes of the people based on the truth that the scripture carry.
If you read this ayat carefully. this is in stark contrast with your stated definition of nabi and rasool

Here also. there is indication that Prophets were given books/scripture and messenger will come to confirm the scriptures.
