No. Not all. An 02 sensor usually lasts longer than 5-6 years, and it may not be the sensor it's self but some are heated, and it is just as likely that the heat circuitry to it is disconnected or faulty. But before I start searching for location(s) are you in California? (Calif has different systems with more sensors)
