With my Citicar (older 3.5 hp GE motor - Alltrax 400 amp 48 volt setup) it would pull just over 400 amps for about 1 second, then start to draw less power as the motor sped up. Even flooring it at a rolling 5 mph the GE 3.5 didn't want to draw more than 350 amps or so.
I now have an Alltrax 7245 (72 volt, 450 amp controller but at 48 volts for now) and it uses the same amount of power at 48 volts - just over 400 amps for the brief time the motor is turning very slowly.
My guess is that the amperage may be limited by the relatively small brush wires in the motor (two per brush) - just about every thing else is heavy duty. In my case a higher amperage controller was somewhat overkill.
I'd imagine your golf cart motor won't draw more than about 450 to 500 amps, particularly because of the low weight.
