To answer your question, here's a quote from The Urantia Book
"The teaching about guardian angels is not a myth; certain groups of human beings do actually have personal angels. It was in recognition of this that Jesus, in speaking of the children of the heavenly kingdom, said: "Take heed that you despise not one of these little ones, for I say to you, their angels do always behold the presence of the spirit of my Father." (113:1.1)
Not everyone has a guardian angel, however. In further reading from the passage given above, we learn:
"Originally, the seraphim were definitely assigned to the separate Urantia races. But since the bestowal of Michael, they are assigned in accordance with human intelligence, spirituality, and destiny."(113:1.2)
