Yes, it definitely does create money when banks take your deposit and then they lend it out. Here is how that works.
Let's say you earn $10,000. That money is already part of the money supply. But when you put it in the bank, it creates more money. You put the $10,000 in the bank and you still have $10,00.
But then they loan out $9000 of it to someone else. Now you still have your $10,000 and that other person has $9,000 and the bank has created $9000 of new money.
Now that person who borrowed $9000 puts it in their bank. Their bank loans out $8100 of it. Now your $10,000 has become $27,100 and there is $17,100 of new money. And so on...
