CREATE TABLE table_55807 ("Position" FLOAT, "Club" TEXT, "Played" FLOAT, "Points" TEXT, "Wins" FLOAT, "Draws" FLOAT, "Losses" FLOAT, "Goals for" FLOAT, "Goals against" FLOAT, "Goal Difference" FLOAT)

What is the goal difference sum that has goals against smaller than 33, draws larger than 13?
SELECT SUM("Goal Difference") FROM table_55807 WHERE "Goals against" < '33' AND "Draws" > '13'
SELECT SUM("Goal Difference") FROM "table_55807" WHERE "Draws" > '13' AND "Goals against" < '33'
