This command is one you run for a database, not for a specific statistic or index or table.

For example, if you add a new column to the table with a default value, no hardcoded statements will have to change as a result to accommodate that change.When you run the Rebuild Index task in SQL Server 2014, you rebuild all indexes, and when you rebuild an index, its statistic is updated with a fullscan.Therefore, there is no need to update Index statistics after you rebuild all your indexes, but you do need to update column statistics. The Rebuild Index task has more options in SQL Server 2016, which is nice for that specific task, but it makes providing guidance about statistics updates a bit trickier.Therefore, if you’re on SQL Server 2016, you probably want to look at more intelligent updates.
