Merry Christmas.
No, it means that even Mary could do nothing pleasing to God, He was however pleased with HIS work IN her.
Men can please other men, but God is only pleased with HIS WORK in them .
Hbr 13:21 Make you perfect in every good work to do his will, working in you that which is wellpleasing in his sight, through Jesus Christ; to whom [be] glory for ever and ever. Amen.
Phl 2:13 For it is God which worketh in you both to will and to do of [his] good pleasure.
He is pleased when we do the works he has foreordained for us to do . That is working His will in you
Eph 2:10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
God was pleased with His work in Mary.
Look to the source of the blessedness not the recipient for praise and glory

"Be merciful unto me, O God, be merciful unto me: for my soul trusteth in thee: yea, in the shadow of thy wings will I make my refuge, until these calamities be overpast." -- Psalm 57:1
