What does a dilution factor of 10 mean?

It means the solution was diluted 10-fold — often written as a '1:10 dilution' — so the concentration is now one-tenth of the original stock concentration.

How does this relate to C1V1 = C2V2?

The dilution factor equals V2/V1 (final volume ÷ initial volume) just as much as C1/C2, since the same relationship (C1V1 = C2V2) links concentration and volume in a dilution.
