I think this is expected: when you use FULL_NAME as a SQL identifier, it
is down-cased, so it no longer matches the uppercase identifier in the
JSON data.  You'd have to do it like this:

SELECT * FROM JSON_TABLE(jsonb '{
         "id" : 901,
         "age" : 30,
         "*FULL_NAME*" : "KATE DANIEL"}',
                '$'
                COLUMNS(
                     "FULL_NAME" varchar(20),
                     ID int,
                     AGE int
      )
   ) as t;

so that the SQL identifier is not downcased.
