I wouldn't say it's partially correct, I would just say that the drive
motors used in RC (radio controlled) cars are picked out to make the car go
fast, and hence require a lot of current to produce this speed. They are
readily available at hobby stores, generally high quality, mostly run on
7.2-9.6 volts, and are usually about the same diameter with the same
predrilled/tapped mounting holes, making them suitable for all kinds of
small projects including (as we are all by now painfully aware) robots.
