Exactly. Churches (denominations) are comprised of fallible human beings. Catholic and protestant alike are run by fallible human beings.

We are all sinners, and no human being other than Our Lord and His Mother was without sin since the Fall. The Pope is also a sinner, just like the rest of us. We Catholics distinguish between the Pope's impeccability as a person -- they are ALL sinnes -- and his infallibility on doctrinal matters of the Church -- which has infallibility not by his own power, but by the protecting Holy Spirit, sent by Our Lord, which guides the Church's Magisterium to preserve and teach the Deposit of Faith in Scripture and Tradition. It is through the Holy Spirit that the Church Magisterium can be secured against hell ever prevailing against it, as Christ promised.

Mary was not sinless. She was born into sin just like the rest of us and knew her Son was her Saviour, just like he is ours.
