In Java Edition 15 mob types can spawn in Windswept Gravelly Hills — hostile mobs: Creeper, Skeleton, Slime, Spider, Zombie and Enderman and 2 more; passive mobs: Sheep, Chicken, Pig, Cow and Llama; ambient mobs: Bat; underground water mobs: Glow Squid.
Creeper, Skeleton, Slime and Spider share the highest spawn weight among the hostile mobs: 100 of 515 (19.4% each) in Java Edition.
Yes. Java Edition lists 15 spawn entries for Windswept Gravelly Hills, Bedrock Edition 15. For example, Skeleton has a weight of 100/515 (19.4%) in Java and 80/495 (16.2%) in Bedrock. Use the edition switch above the tables to compare.
Each spawn attempt first picks a category (for example hostile or passive mobs), then one mob of that category at random, weighted by its spawn weight. A mob's chance is its weight divided by the total weight of its category in the biome — so the shares in each table add up to 100%.
