Your spot on a scale is your ranking. If your football team has a #10 ranking and you’re playing #1, well good luck. Your class ranking is how you measure up. The student with the highest ranking is the valedictorian.
All kinds of things have rankings, from the top 100 colleges in the US to a person's constantly updated list of favorite horror movies. Athletes and the teams they play for have rankings too. In the military, someone who has a higher rank, or position, than anyone else who's present might say, "As the ranking officer, I'll command the troops to retreat."
