There is no "Update Nine" for Minecraft. Versioning uses:
1.21 (Tricky Trials, June 2024), snapshots 24wXXa.1.21.0 (same content), beta 1.21.10.Updates release simultaneously on all Bedrock platforms (Xbox included).
Ignore clickbait videos claiming "Update 9" or "1.9" (that was Combat Update, 2016).
