I don't think anyone has a single agreed upon number for the water consumption, with the higher estimates focusing on a lot of wider externalities and the lower estimates ignoring them, such as ignoring the cost of training.
it doesn't have to be agreed upon but even the largest estimates don't come even close to how much corn farms use
> The water usage of 260 square miles of irrigated corn farms, equivalent to 1% of America’s total irrigated corn.

Roughly 1% of corn is used for actual food consumption btw.
