I think this is correct.
Suppose she has a 4-gallon bucket, 3/4 filled. She has “less than 4 gallons.”
Contrast with a milk crate, which normally holds 4 jugs of milk, but it, too is only 3/4 filled. Same liquid volume of milk but now I would say that she has “fewer than 4 gallons”, because the milk now comes in discrete units.
