Actually, you left out a very important word. What Apple REALLY says on that page is the following. Please notice the word I placed in bold print:
Can I keep using my 32-bit apps?
Yes, you may continue to use 32-bit apps with your Mac today. Using 32-bit software has no adverse effects on your data or your computer.
Now do you get it? In other words, 32-bit apps will continue working for the time being, and will have no adverse effects, but that will totally change with the release of 10.15. At that point, they will be dead in the water.
For those of you who haven't read it yet, MarkandKeren are referring to this page:

I hope this info is helpful. Please let me know. Thanks!
