I don't think that is possible however you can try this

Update : In as well as inner join can be used

Declare @Sample table 
(
UserID int,
col2 int
)
INSERT INTO @Sample
SELECT 1,50 UNION ALL
SELECT 1,100 UNION ALL
SELECT 2,150 UNION ALL
SELECT 2,200 union all
Select 4,500

DeLETE FROM @Sample  
WHERE UserID IN (SELECT UserID
             FROM @Sample 
             GROUP BY UserID
             HAVING COUNT(*) > 1)


 Delete O
 FROM @Sample O
 INNER JOIN 
 (
  SELECT UserID 
  FROM @Sample  
  GROUP BY UserID
 HAVING COUNT(*) >1
 ) X
ON O.UserID = X.UserID

The answer which i originally posted :

Delete O
FROM UserPredictions O
INNER JOIN 
(
 SELECT UserID 
 FROM UserPredictions  
 GROUP BY UserID
 HAVING COUNT(*) <500
 ) X
ON O.UserID = X.UserID
