The short answer is, no, you don't need to worry about paying rent for the time being. Yet, in no way does this let you off the hook for paying back rent for the time you have resided in the property, should you ultimately come to an agreement with the bank (or new owner) to continue renting the condo.
Have you been contacted by the bank since the property was foreclosed on? Provided you are a renter, in California you will be provided sixty (60) days written notice to vacate the premises; in the case of residential property, I have never heard of an instance where a bank asked the tenant being kicked out to pay rent in the interim.
If you have further questions or concerns, feel free to contact me directly.
