The Catholic Church does not say that it takes miracles to become a saint. The word “saint” comes from Latin “sanctus”, which means “holy”. One can apply it to everyone who is holy, living or dead. There is a narrower meaning of the term, namely “those who are in heaven”. That is presumably a vast multitude. In the Catholic Church there is a “Feast of All Saints” celebrating and honoring all those in heaven. Finally, there is the narrowest meaning of the term, which is those who are held up by the Church as examples of sancity -— the “canonized” saints. The Catholic Church believes that the “canonized” saints are a tiny subset of all the saints in heaven.
All that Jesus justifies are holy. Saint means set apart, aso. All that Jesus owns are set apart from those who will perish. All of those chosen by God to be saved are saints.
And I firmly believe that all of those who are in heaven right now are too busy praising God to be concerned about what is going on down here. They aren’t listening to your prayers, Jesus is. Pray to him, that is what he is there for. You don’t need help to talk to God, and God doesn’t need the help of the saints to listen. God already knows your needs.
