Does the 1:1 ratio of wise virgins to foolish ones have any significance?

We see in Mtt 25:1-13 Jesus presenting the Parable of Ten Virgins. Of the ten, five are wise , anticipate delay in arrival of the groom, and stock enough oil to last through the ceremony. Five are foolish and are not prepared for unanticipated events. The ratio of wise and foolish virgins is one to one. Elsewhere, Jesus says that a few out of the many invited, are chosen for the reward of eternal life ( Mtt 22:14). My question is : According to Catholic scholars, does the ratio of wise virgins to foolish ones have any significance ?
