My comment was about 32 bit code in general, not just about Ubuntu. There is no end of 32 bit support, neither on Windows nor on Linux (the kernel itself can run even on a 486 IIRC) and AFAIK even macOS can still run 32 bit code. Of course individual distributions like Ubuntu can drop 32 bit support (and personally i do not see it as much of an issue since you can switch distributions and Valve can simply recommend one that doesn't arbitrarily break their users' programs), but that is just the distribution doing it. The kernel can still run 32bit code and with enough effort even 19.10 will be able to run 32bit programs, the whole hubbub is about avoiding that effort.
