To clarify, my answer was intended to explain item drop rates in Terraria, specifically.

Different games work differently, you won't have any single method that works for every game.

Depending on which particular game you want to find item drop rates for, it may be as simple as looking at the game code. Or the algorithm for calculating them may so complex that there's no human way of interpreting the drop %'s. Or you may not even be able to get access to the game code.
