Minecraft wiki entry for Overworld, associated text: A given seed generates almost exactly the same world every time, provided the same edition, game version, and world type are used. Although the exact spawn point varies, the coordinates of all terrain features are the same. All seeds within the 32-bit integer limit in Java and Bedrock editions may also generate worlds with the same terrain shape and biome map, but the placement of terrain features, structures, and carver caves may differ.
