That's partially true. 32-bit apps will not work in Catalina, and some of your 64-bit apps may have to be updated (if an update is available) for them to work.

For example, I always used MS Office 2008 (32-bit) pre-Catalina but it stopped working (and the apps won't even launch) in Catalina. I knew about this in advance and was ready for it. If you want to check compatibility before upgrading, explore https://roaringapps.com
