Incorrect. Higher numerical gears can create quicker acceleration, but for a shorter distance due to winding the engine out of the power band faster. Numerically lower gears result in slower acceleration, but a higher top speed.
Lower numerical numbered gearing per revolution is generally referred to as "tall" and higher numerical gearing is generally referred to as "short".
Tall gearing gives higher Vmax @ engine redline vs short gearing, hence tall is used for fuel economy since engine turns slower for same road speed.
Manufacturers are adding more and more gears to take advantage of both aspects with the TCU algorithms doing all the math (and shifting) for whatever is called for at the time. Think our DSGs race to 6th gear now, wait til they add the other cog. I remember when 3 gears were plenty (3 on the tree) because torque is king
