does masturbating 1 to 2 times a day make you have a low sperm count?

It reduces it temporarily and also the volume of semen ejeculated, but not the rate of production.  That’s why if you’re getting a fertility test done, or providing the speed of IVF treatment they will tell you not to have sex (including masturbating) for a minimum of three days before providing the sample 

Short term only.

A normal healthy male will produce millions and millions of sperm over a lifetime - and there's literally no way to squirt them all out by jerking off.

If a man is trying to impregnate a woman, then he should obviously stop masturbating in order to give his sperm the ability to build up.

Temporarily, yes to some extent. But getting off frequently doesn't affect fertility. Genghis Khan managed to have hundreds of children. 

If you went in for a test while wanking yourself to the point of perpetual depletion there would of course be less sperm in the sample. Whether or not it will be high, low or of good quality after you stop masturbating for a few days boils down to individual factors like health, fitness, lifestyle, age, etc., but doesn't have much of anything to do with history of masturbation. 

Not really... Your body generates sperm constantly, so even if you ejaculate, the "shortage" does not last that long.
