Soy milk splits when mixed with coffee though, and doesn't really have a neutral enough taste, for that I find oat milk works great.
I can't tell if it's a change in cultivar or transcontinental transport, but something bad happened with almonds in Europe.
A more reputable source would be https://ourworldindata.org/environmental-impact-milks which lists almond milk as half the freshwater volume of dairy milk, and far better at every other metric (land use, greenhouse gas emissions, and eutrophication).
So you'd have to stretch things much farther than you did in your post for dairy milk to have an edge over almond milk. And even if you somehow did it, then dairy milk would have to then beat out soy milk which is even better than almond milk in all of these metrics, which it won't. If you care about environmental impact, dairy milk just isn't going to be in the cards. Let it take the L.

These were just two of the several sources I found, at each extreme. There was similar variation for cow milk.
Considering that it takes roughly 1 gallon of water to produce 1 almond, and that 23 almonds wouldn't fill even an 8oz cup, I'm guessing that the higher end of the spectrum is probably more accurate for almond milk.
It also looks like almond milk has half the calories per gallon of skim milk and 1/4 that of whole milk.
