Prayer is definitely very effective, more so then any words we could say to someone or examples we could show them, because when we pray, it is purely God who takes action, He may work through us, but it is by His power that prayer is effective, and although people may reject graces in this life and not be all that devout, your prayers and penances can still beg pardon for their sins when they die, which can result in their salvation,
here is a devotion, a very easy one, called “Devotion to the Drops of Blood Lost by our Lord Jesus Christ on His Way to Calvary”
*"St. Elizabeth, Queen of Hungary, with St. Matilda and St. Bridget, wishing to know something of the Passion of Jesus Christ, offered fervent and special prayers, upon which Our Lord revealed to them:
To all the faithful who shall recite for 3 years, each day, 2 “Our Fathers”, 2 “Hail Marys” and 2 “Glory Bes”, in honor of the drops of Blood I lost, I will concede the following 5 graces:
1st The plenary indulgence and remittance of your sins.
2nd You will be free from the pains of Purgatory.
3rd If you should die before completing the said 3 years, for you it will be the same as if you had completed them.
4th It will be upon your death the same as if you had shed all your blood for the Holy Faith.
5th I will descend from Heaven to take your soul and that of your relatives, until the fourth generation."*

and yes there is a very definite chance your prayers will be answered if you pray the rosary and divine mercy, as long as what you’re asking for is not harmful to yours or anyone elses soul,
here are the 15 promises to those who recite the rosary -
The Fifteen Promises of Mary to
Christians Who Recite the Rosary
** 1.** Whoever shall faithfully serve me by the recitation of the Rosary, shall receive signal graces.
** 2.** I promise my special protection and the greatest graces to all those who shall recite the Rosary.
** 3.** The Rosary shall be a powerful armor against hell, it will destroy vice, decrease sin, and defeat heresies.
** 4.** It will cause virtue and good works to flourish; it will obtain for souls the abundant mercy of God;
it will withdraw the hearts of men from the love of the world and its vanities, and will lift them to the desire of eternal things.
Oh, that souls would sanctify themselves by this means.
** 5.** The soul which recommends itself to me by the recitation of the Rosary, shall not perish.
** 6.** Whoever shall recite the Rosary devoutly, applying himself to the consideration of its sacred mysteries
shall never be conquered by misfortune. God will not chastise him in His justice, he shall not perish by an unprovided death;
if he be just he shall remain in the grace of God, and become worthy of eternal life.
** 7.** Whoever shall have a true devotion for the Rosary shall not die without the sacraments of the Church.
** 8.
Those who are faithful to recite the Rosary shall have during their life and at their death the light of God and
the plentitude of His graces; at the moment of death they shall participate in the merits of the saints in paradise.
** 9. I shall deliver from purgatory those who have been devoted to the Rosary.
** 10.** The faithful children of the Rosary shall merit a high degree of glory in heaven.
** 11.** You shall obtain all you ask of me by the recitation of the Rosary.
** 12.** All those who propagate the holy Rosary shall be aided by me in their necessities.
** 13.** I have obtained from my Divine Son that all the advocates of the Rosary shall have for
intercessors the entire celestial court during their life and at the hour of death.
** 14.** All who recite the Rosary are my sons, and brothers of my only Son Jesus Christ.
** 15.** Devotion of my Rosary is a great sign of predestination.
(Given to St. Dominic and Blessed Alan)
