The following example creates single-column statistics for all eligible columns for all user tables in the AdventureWorks2022 database by executing sp_createstats. Then, sp_helpstats is run to find the resultant statistics created on the Customer table.

USE AdventureWorks2022;  
EXEC sp_createstats;  
EXEC sp_helpstats   
@objname = 'Sales.Customer',  
@results = 'ALL';  

Here is the result set.
