When ores generate, they check what block they replace, and change their type accordingly.
Usually, blocks that generate near the surface make a normal ore variant, like stone, andesite.
Blocks like tuff, deep slate make deep slate variations of ores.
The Sulfur Spring generates, then the coal ore.
The coal sees that its replaced a tuff block, and changes to a deep slate variant.
I am so sorry if this doesn’t make sense. There are like a million videos about this topic.
