The Most Holy Rosary of The Blessed Virgin Mary is a prayer chaplet, the main prayers are the Our Father/Lord’s Prayer and the Hail Mary. Someone once asked me what is the “Hail Mary?” The Hail Mary is two Holy Bible Verses, acknowledgement that we are sinners (People do things that are not always right), and asking St. Mary to pray for us.
The Holy Bible notes the acknowledgement of being a sinner.
We ask people to pray for us all the time. I like asking the person who God saw as good enough to visit Earth through.
