No, and the Holy Trinity is derived from the Bible but not spelled out as such. As Catholics we believe in the Mystical Body of Christ which is divided into the Church Alive in Heaven and the Church Alive on Earth today. This is the Communion of Saints Jesus Christ is the Head of the Church and the rest are the Members and Organs of that Body.
If we here on earth alive can pray for one another interceding for one another asking Christ to help ourselves and others then why can't the Church Alive in Heaven can't do so. This is explained in the Catholic Encyclopedia:
"The Catholic doctrine of intercession and invocation is set forth by the Council of Trent, which teaches that "the saints who reign together with Christ offer up their own prayers to God for men. It is good and useful suppliantly to invoke them, and to have recourse to their prayers, aid, and help for obtaining benefits from God, through His Son Jesus Christ our Lord, Who alone is our Redeemer and Savior. Those persons think impiously who deny that the Saints, who enjoy eternal happiness in heaven, are to be invoked; or who assert either that they do not pray for men, or that the invocation of them to pray for each of us is idolatry, or that it is repugnant to the word of God, and is opposed to the honor of the one Mediator of God and men, Jesus Christ" (Sess. XXV). This had already been explained by St. Thomas: "Prayer is offered to a person in two ways: one as though to be granted by himself, another as to be obtained through him. In the first way we pray to God alone, because all our prayers ought to be directed to obtaining grace and glory which God alone gives, according to those words of the psalm (lxxxiii, 12): `The Lord will give grace and glory.' But in the second way we pray to the holy angels and to men, not that God may learn our petition through them, but that by their prayers and merits our prayers may be efficacious. Wherefore it is said in the Apocalypse (viii, 4): `And the smoke of the incense of the prayers of the saints ascended up before God from the hand of the angel'" (Summ. Theol., II-II, Q. lxxxiii, a. 4). The reasonableness of the Catholic teaching and practice cannot be better stated than in St. Jerome's words: "If the Apostles and Martyrs, while still in the body, can pray for others, at a time when they must still be anxious for themselves, how much more after their crowns, victories, and triumphs are won! One man, Moses obtains from God pardon for six hundred thousand men in arms; and Stephen, the imitator of the Lord, and the first martyr in Christ, begs forgiveness for his persecutors; and shall their power be less after having begun to be with Christ? The Apostle Paul declares that two hundred three score and sixteen souls, sailing with him, were freely given him; and, after he is dissolved and has begun to be with Christ, shall he close his lips, and not be able to utter a word in behalf of those who throughout the whole world believed at his preaching of the Gospel? And shall the living dog Vigilantius be better than that dead lion?" ("Contra Vigilant.", n. 6, in P.L., XXIII, 344). "
Catholics don't worship our Blessed Mother but we give her honor as the mother of Jesus Christ. She is the highest of all Creation being born just a lowly human of flesh and blood. Through her humility and complete devotion to God she earned this title and position as Queen of Heaven. She is not God though. But if we imitate the Blessed Virgin we will gain to see the Blessed Fruit of her womb Jesus Christ.
Every fallen angel fell rejecting some aspect of Jesus Christ. Some rejected Christ's Infinite Mercy. Some His Infinite Compassion. Satan fell rejecting our Blessed Mother Mary.
