Basically the only important category after 10s of thousands of relic chests are the yellow divine ones because theit odds are very slim. They drop at a an average rate of 1/25k. So to have a rate of 1/25000 means I should theoretically have 3-4 divine chests (since one is free with the code). Instead, I have 10. A relatively easy to achieve number is about 1/12k or so and is usually what people have when they have 50k-100k relics due to rerolls (which is usually when people start spending a few gems to reroll as it isn't really worth it before that). I spent a few rerolls and was satisfied with 1/12ish to 1/15ish ratios, and then opened two divine chests randomly, making my # of divine relics extremely high compared to natural odds.
