In Java Edition 3 mob types can spawn in Basalt Deltas — hostile mobs: Magma Cube and Ghast; passive mobs: Strider.
Magma Cube has the highest spawn weight among the hostile mobs: 100 of 140 (71.4%) in Java Edition.
Yes. Java Edition lists 3 spawn entries for Basalt Deltas, Bedrock Edition 3. 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%.
