No deadlock in transaction guarantee

If I have 2 different transactions which: Both only update records from the same table and the first line in the transaction is a select for update (which locks all records touched in the rest of the transaction).

But the where clauses are different, for instance in transaction A it is: where id in (1, 2, 8) and in transaction B it is: id >= 0 and id <= 10. Is it then guaranteed that both transactions never deadlock ?
