My whole part in this
But they're fruitless in their harvesting
Though they are aware of the Game’s existence, they do no not where he fits in the grand scheme of things
The Game=The Devil. The fruitless in their harvest could refer to adam and eve harvesting the apple from the tree. I think this also ties into the 2nd and 4th lines. 2nd line could refer to humanity as the race and 4th line saying that the devils tempting of adam and eve with the fruit is the reason humans became corrupted.
