Learning comes with listening.

The more you listen the more you pick up subtle differences.
When you know what these subtle differences are then you may need something to distinguish them when describing them. You're trying to do it the other way around.

You said they all sound the same for you, so you're not in the position of needing to know.

In other words, it's not important, just carry on listening to music and don't worry about it.
