All these soil types have a surface layer or the A horizon. These soils also have subsoils or a Bt horizon, parent material that is A C horizon, and bedrock or the R horizon.

In soils with distinct soil horizons, the bottom zone is the bedrock denoted as R.
heavy rains in this climate zone can remove, or leach, nutrients from the topsoil.
No, they do not. They are "old soils" and contain very few nutrients.

C - generally infertile tropical soils
Areas with heavily leached soils, usually in tropical or previously tropical areas.

Tropical soils are often poorly fertile. This is because heavy rainfall leaches out nutrients.
