MySqli Put IF in Select Query

How can this code convert to correct query? Is it possible?
first i want check if id IN (55,1454,232,444,10999,223) is exists rows. second if not exists get rows by random.

 SELECT
      id
      name
      title
 FROM
      table t
 WHERE
      id IN (55,1454,232,444,10999,223)

 IF count_row(t) == 0 // <-- if for WHERE no result row
      SELECT
           id
           name
           title
      FROM
           table
      ORDER BY RAND()
      LIMIT 20
