This isn't accurate.

The most popular Steam OS is Windows 7, 64bit.

Steam usage data shows the the overwhelming majority of Windows 8 
installs are 64-bit, so newer Windows installs are 64-bit almost 
as a rule.

Old Microsoft posts show a surge in 64-bit installs.

Modern Microsoft and Sony consoles use 64-bit processors.

Smartphones and tablets are a notable exception, probably due to 
their lower memory requirements, but this won't last forever.

So I don't think it's fair to say "most computers aren't 64-bit." 
A good fair chunk of computers are.
