A job opening being posted offers no important information about the situation inside any company, nor about the count of applications that have been received, nor the count that has been ignored or rejected.
For most of us, not having a job represents having a much higher risk of death. The conditions of workers are essentially conditions of work or die.
If you think workers have as much bargaining power as companies, then you are, frankly, deluded. You may personally not notice the depth of the disparity, due to your having certain privileges, but you are still giving a distorted representation of your own conditions.
