I think you can understand how for example an engine works, in a way which couldn’t be described as subjective or artificial. You might have a shallow or deep understanding of this depending on your profession. People who are religious tend to talk about belief rather than understanding. I don’t suppose many Christians claim to understand God’s mind or his will, quite the opposite. Also, claiming to know God’s will as zealots do is not the same as understanding it.
