This is how it works. So first lets talk about the height. When it first starts generating it picks a random height from 5 to 12. As the terrain generates it picks a random height again instead from -1 to 1 -1 = down one 0 = same as before 1 = up one Secondly, how it builds the terrain and rarity. First Is the stone. it takes the height and stamps the costume its on, changes Y position by 14 and stamps again, etc. is does that over and over until it stamps how ever many height is ( it takes away 2 from height so grass and dirt can fit.) As it changes costume, it picks a random costume from stone to stone, to stone, to stone, to stone, to emerald ore, to emerald ore, to emerald ore, to noah40225 ore, to noah40225 ore, to ruby ore. Which ever one it picks is stamps it. That's rarity in a nutshell. then it stamps 2 dirt and 1 grass block then it picks a random number 1 to 10, and if its 1, it stamps grass. It does all that surprisingly fast.
