"Does anyone know why Apple has took decisions to support only 64-bit software only?"
This is really hard for me, there are many and multiple old software which does not have 64-bit software or they won't bring 64 bit as a new update.

About the transition to 64-bit technology and how it affects 32-bit apps.
Apple began transitioning to 64-bit hardware and software technology for Mac over a decade ago, and all modern Macs now include powerful 64-bit processors that can run advanced 64-bit apps. These apps can access dramatically more memory, enable faster system performance, and take advantage of technologies that define today's Mac experience.
Apple has been working with developers to transition their apps, and in 2018 Apple informed them that macOS Mojave would be the last version of macOS to run 32-bit apps. Starting with macOS Catalina, 32-bit apps are no longer compatible with macOS.
For all 32-bit apps, please contact the developer of the app to learn whether an updated version of their software is available or planned.

With the release of macOS 10.15 Catalina, applications will have to be 64-bit. App developers will issue updated apps if they want their apps to work on this newest macOS upgrade
