Answer 1

If you don't want to use MERGE, you can try:

begin
   INSERT INTO users VALUES(1,10);

   exception
      when dup_val_on_index then
         update users
            set points = 10
          where id = 1;
end;

Answer 2

MERGE INTO users u
USING (SELECT 1 as id FROM dual) a
ON a.id = u.id
WHEN MATCHED THEN UPDATE SET u.points = 10
WHEN NOT MATCHED THEN INSERT (id, points) VALUES (1, 10);

Answer 3

You would need to use a MERGE. Something like

MERGE INTO users dest
  USING( SELECT 1 user_id, 10 points FROM dual) src
     ON( dest.user_id = src.user_id )
 WHEN MATCHED THEN
   UPDATE SET points = src.points
 WHEN NOT MATCHED THEN
   INSERT( user_id, points ) 
     VALUES( src.user_id, src.points );
