Had Dumbledore told harry the prophecy after Quirell defeat ,what would had happened ?

When harry ask Dumbledore why Voldemort targeted his parents,instead of refusing to answer ,Dumbledore goes on a long explanation to harry that there is a prophecy,about some chosen one with the potential to beat Voldemort ,and that voldemort attacked his house because Harry potentially was the Chosen One ,and Voldemort decided to kill all those potential chosen ones when they are weak and unable to contest him .

So ,what would be harry ́s reaction ?Would this change anything ?
