Prayers go up to Mary, to the Saints. I’m sure Jesus wonders why they aren’t directed to Him.
All have fallen short, even Mary. All praise is due Jesus, no other. Paul was a great Christian post-Damascus road. Yet, he’s not worthy of receiving prayer.
Only one name by which we may be saved - Jesus.
The misunderstanding arises from the older meaning of the verb "to pray" - it originally meant simply to ask. When we "pray" to a saint (or to the Blessed Virgin), we are not worshiping that saint - we are simply asking him or her to join us in praying to Jesus.
At the end of the Rosary, the final prayer makes this quite clear:
"Pray for us, holy Mother of God, that we may be made worthy of the promises of Christ."
"Let us pray [i.e. we haven't been praying in the newer sense before].
"O God, who by the life, death, and resurrection of thine only begotten Son, hath gained for us the fruits of everlasting life: grant that we, in meditating upon the mysteries of the holy Rosary, may imitate what they contain and obtain what they promise; through the same Christ our Lord. Amen."
It's that time thing again. The great saints in heaven stand outside time, and they can be asked to pray with us and for us, just as we might ask a particularly righteous friend on earth to join us in prayer.
