Interesting that you only quoted the first part of the Psalm and not the part that is important for determining the full context.

You quoted Romans 3 against the Immaculate Conception. Psalms 14 and 53 both contrast the godless unrighteous with God’s people. So you are taking the verse out of context unless you are asserting Mary was one of the fools who say there is no God.
