AFAIK, lactose intolerance is a spectrum. I come from a country with spotty lactose tolerance so I've known multiple intolerant people. Just to give you an example:

I am mildly intolerant. I can have a small glass of whole milk with some discomfort, namely gas and bloated stomach. People who are highly intolerant would have a really, really bad time with the same amount with cramps, diarrhea and whatnot.

Me too. I can drink half a glas of whole milk, eat all the cheese except for tête de moine, and eat half a block of butter, without a problem.

If it comes to a situation where it's impossible to avoid consumption of high in lactose products, I drink the lactose-free milk and do not take the enzymes (lactase). The milk already contains a lot of lactase. The enzyme tablets do not work with me somehow :)
