Legacy System Extension Notice After Installing Windows Boot Camp. Will my current apps no longer work, once there is a future version of Mac Catalina?

I was curious about this notice, "Legacy Systems Extension.'' It says whatever app/software titled, and explains that it won't be compatible with a future version of Mac OSX. It tells me to contact my developer, or learn more.

This was right after I had installed Windows Boot Camp, alongside my Mac. Every time I switch over/restart to my Mac after leaving Windows 10, I get this notice.

What does this mean? And I need a simple explanation, I've been confused by how recent articles and sites, have discussed it.

macOS Catalina and future macOS versions no longer support 32-bit macOS applications. It is unrelated to Windows.

Check under About This Mac-> System Report -> Legacy Software.
