 The "size" of a black hole might be identified as the radius of
the event horizon, since there is no way of looking inside the
event horizon.  The radius of a black hole's event horizon is an
increasing function of the mass of the black hole.  (My memory
tells me that the radius is a linear function of the mass, but
that should not be taken as reliable.) 

Your memory is correct (at least when angular momentum and charge are ignored) - the Schwarzchild radius is 2Gm/c².

Either the Earth or the
Sun would have (if it were a black hole) an event horizon radius
of more than one millimeter, but that statement too is a product
of my not-always-reliable memory.
 

For the Earth, it's about 9mm and for the Sun, around 3 km.  So yes, both over 1 mm.

 

Finally note:  An electron can be modeled in QCD as if it were a
black hole with the mass, charge, and spin of an electron. ...

 Electrons are color neutral.  As far as QCD is concerned (since
QCD is only about the strong force, i.e. the color field),
electrons are invisible.  (Disclaimer: to the best of my
understanding; I am not a physicist.)

Perhaps he meant QED, rather than QCD.
