It is not so much about free will as it is about the fact that God wishes it to be this way. God could in reality give everyone free will and at the same time ensure that everyone lives holy and blameless lives much as Mary did.
I agree, I believe your above statement is absolutely correct.
MARY WAS FREE FROM ALL PERSONAL SIN John Paul II
“Testifies that Mary,
free from original sin, was also
preserved from all actual sin and that this
initial holiness was granted to her in order to fill her entire life.
Trent expresses this conviction, affirming that
no one can avoid all sins, even venial sins, throughout his life,
unless he is given a special privilege, as the Church holds with regard to the Blessed Virgin (DS 1573).
The Council of Trent asserts, a special privilege
guarantees this immunity from sin. And this is what happened with Mary.
The
special privilege granted by God to her who is all holy leads us to admire the marvels
accomplished by grace in her life.”

God has given to Mary
all the graces necessary for not to commit even a smallest act of sin.
.
The same principle applies also to all of us, if God would willed, He could give all of us
all the graces necessary for not to commit even a smallest act of sin and would be no sin in this world.

310 But why did God not create a world so perfect that no evil could exist in it? … God freely willed to create a world in a state of journeying towards its
ultimate perfection.
.
302 The universe was created in a
state of journeying (in statu viae) toward an
ultimate perfection ( 314 Through
the dramas of evil and sin) yet to be attained, to which God has
destined it. God protects and
governs all things which he has made.
.
308 The truth that God is at work in
all the actions of his creatures is inseparable from faith in God the Creator.
God is the
first cause who operates in and through
secondary causes: "For God is at work in you,
both to
will and to
work for his good pleasure."171
.
St. Thomas teaches that God
effects everything, the
willing and the
achievement. S. Th.II/II 4, 4 ad 3:
St. Thomas also teaches that all movements of will and choice must be traced to the divine will: and
not to any other cause, because
Gad alone is the
cause of our
willing and
choosing. CG, 3.91.
.
Pr.9:10; The fear of the LORD is the beginning of wisdom, and knowledge.
.
324
Faith gives us the certainty that God would
not permit an evil if he did not cause a
good to come from that very evil, by ways that we shall fully know only in eternal life.
I have a reverent healthy fear of God, but I have zero fear of hell because,
faith gives me the certainty, so I believe,
God would NOT permit an evil if he did not cause a good to come from that very evil.

God bless
