It's nitpicking. You can make 500 steps vs 100, and make a headline-like claim that it's five times more. In real life difference is negligible. Your organism requires walking in significant doses, and for you to practice it, you have to live in a walkable space (it includes infrastracture, and safety). A city can be driven by public transport, and not be pedestrian-friendly. A city can be private-car driven, and not be pedestrian-friendly.
