Why Doesn't The Automatic Colorize Tool Work?

This old blank and white photograph has been automatically colorized, using Photoshop Elements 2020. As anyone can see, the tool hasn't done much at all. I know that I could use the section tool, choose colors, and colorize this picture manually. But, Adobe claims that Photoshop 2020 should colorize old photos, like this one, automatically. I have read, and watched the tutorials. This picture has been formatted correctly, and everything was done in accordance with the instructions. This tool just does not work very well.
