There is no specific requirement to have Serverless to enable Predictive Optimization. 
You must fulfill the following requirements to enable predictive optimization:

• Your Databricks workspace must be on the Premium plan or above in a region that supports predictive optimization. See Databricks clouds and regions.

• You must use SQL warehouses or Databricks Runtime 12.2 LTS or above when you enable predictive optimization.

• Only Unity Catalog managed tables are supported.
  
  
  Please refer to this doc: https://docs.databricks.com/en/optimizations/predictive-optimization.html

Thanks for your answer, One more question on this, I think in case to use predictive optimization we should first enable this at account level ? If this is the case then by doing this each of the catalogue/schema/table in Account will start using predictive optimization? should we first disable this for list of catalogues where we do not want this to be used using "ALTER CATALOG [catalog_name] DISABLE PREDICTIVE OPTIMIZATION;"" before enabling at Account level ? 

Thanks. This was answered in https://community.databricks.com/t5/administration-architecture/enable-predictive-optimization/td-p/...

The documentation states this:

Predictive optimization identifies tables that would benefit from ANALYZE, OPTIMIZE, and VACUUM operations and queues them to run using serverless compute for jobs.

If I don't have serverless workloads enabled how does predictive optimization optimizes the tables?
