Limit number of records returned by view

I have one view and this view returns more than 5.000 records.
I want to return only one record. All records are created on the same day so I cannot use sorting by CreatedOn column.

I used FetchXML Builder to modify view definition and now it is like this:

<fetch version="1.0" top="1" output-format="xml-platform" mapping="logical">

When I execute this view in FetchXML Builder i get only one row in results.

After I saved this view in CRM I tried to get records and I still see more than 5.000 records.
The requirement is to return only one record.

CRM version: 1612(9.0.19.8) (DB 9.0.19.8) on-premises
