In scripture, the reality always exceeds the metaphor. Satan is depicted as a snake. But he is much deadlier than any snake. Jesus is depicted as a lion. But his power far exceeds that of a lion.
Therefore, when Jesus promises that the righteous will be as numerous as the stars in the sky and more than the sand on the seashore, we can be confident that the righteous will not only exceed the wicked, they will seriously outnumber them!
This is what we in Christian circles call, a victory.
