it`s less than half the truth... 1/3rd actually...
load and impedance are the other 2/3...

eg: if a motor pulls 20amps with a particular load at 10volts, then it may pull 10amps at 20volts with a much smaller load...

so no, voltage to current isn`t that simple, nor there is anything stationary/static when it comes to current draw... the load progresses/varies when driving an r/c, and so does current draw... same can be said with voltage [batteries aren`t power supplies with imaginary/perfect/static behaviour] and motors as well...

as a general expression, a motor will pull more current when accelerating from a dead stop [large load] and the current will dive as speed advances [depending on rpm/v, the dynamic impedance increases with speed advance].

it can be analyzed with math to reach 'legitimate' conclusions, but we might not need to go there...
