Ratios and what do they mean relative to each other.

If you have 5 players, each with a win/loss ratio that varies according each individual player and you add up all those ratios and divide by the 5 players, what does the resulting ratio mean in relation to each other.

Suppose player 1 is 1.5, player 2 is 3, player 3 is .8, player 4 is .7 and player 5 is .9.

If you add up all these ratios and divide by 5 to get the average, you get an average ratio of 1.38. What does this ratio mean? Does it mean that the players have a 1.38 ratio of win to loss? If so how does that make sense when in the win to loss spread the addition of the numbers should equal 0, i.e. There should be an equal amount of losses as there is to wins.

I'm sorry if the question is a bit confused, or muddled but any help would be appreciated.
