Are these unix exe files and others 32-bit code, & should I do something about them before moving to Catalina?

I am running Mojave 10.14.6 (on a late 2013 MacBook Pro), waiting to upgrade to Catalina. Checking for 32bit applications lead to a list containing /System/Library/Frameworks/DiscRecording.framework/Versions/A/Resources/draudiotool /System/Library/Frameworks/AppKitScripting.framework/Versions/A/AppKitScripting /System/Library/PrivateFrameworks/vmutils.framework/Versions/A/vmutils /System/Library/PrivateFrameworks/CoreMediaPrivate.framework/Versions/A/CoreMediaPrivate (which seem to be mostly Unix executable files), some dynamic libraries, a few apps, and then some items like this /sbin/autodiskmount /usr/sbin/pictd /usr/lib/libnetsnmp.5.2.1.dylib /usr/bin/qc2movie Are these 32-bit code files that are going to block the use of apps, even if the apps are 64-bit? Will installing Catalina remove them, or should I delete them first? I can delete the apps (don’t need or can upgrade them), but is there anything I can do ahead of time with this list?
