On the contrary. An implicit reference ca be found in the angel’s greeting to Mary in Luke 1:28: "Hail, full of grace, the Lord is with you." The phrase "full of grace" is a translation of the Greek word kecharitomene. This word represents the proper name of the person being addressed by the angel, and it therefore expresses a characteristic quality of Mary. Kecharitomene is a perfect passive participle of charitoo, meaning "to fill or endow with grace." Since this term is in the perfect tense, it indicates a perfection of grace that is both intensive and extensive. This means that the grace Mary enjoyed was not a result of the angel’s visit, and was not only as "full" or strong or complete as possible at any given time, but it extended over the whole of her life, from conception onward. She was in a state of sanctifying grace from the first moment of her existence to have been called "full of grace."
All the wordsmithing in the world will not make "full of grace" mean "Empty of sin". Grace simply does not mean sinlessness. Infact it means the opposite, the more Grace God shows to one, the more sin that one has to be overlooked in or do be blessed. The definition of the word forces the notion of the sin remaining, otherwise there is no need for grace.
