That's not quite right, John.

Golf ball dimples generate turbulence, which knocks back the 'lift' (usually drag)

Any spinning sphere with forward velocity will produce the lift you speak of.

Because Golf ball dimples generate turbulence, they help reduce forward velocity drag within a only a certain range of speed. --I'm going off of decades old memory here. But, it follows, that at higher speeds, (out of a gun) the sphere is already producing big turbulence. (no dimples needed to foil the otherwise nicely formed trailing air-pocket of 'lift'.
