No its the other way round.
kV means the motor revs per volt applied so a 950 kV motor will turn off load at battery volts x 950. For example with a 3s LiPo that would be 11.1 x 950 = 10,500 rpm. A 3000 kV motor would turn at 11.1 x 3000 = 33,000 rpm.
Brushless are basically constant speed motors so the rpm at maximum amps is only about 15% lower than at no load.
Too big a prop on a brushless will cause it to try to take too many amps and likely burn out the ESC and/or the motor.
