In general most people planting these gardens "ad-hoc" and not doing it more or less "as a job" probably don't have that much dedicated surface for this, nor can put in that much effort/time into it in order to obtain more than a nice and tasty complement for their meals. If you can consistently offset a shortage for your family then you're pretty much a farmer. And I say this as someone who actually cultivated such a garden for years, with help from the family. I allocated a lot of time each day to tending that garden, more than most people would be able to do these days and have a stable job, even with WFH. It was just a pretty hard but pleasant activity, relaxing, I got fresh air and exercise, and I could get some really tasty vegetables but nothing that could "feed the family". And my livelihood didn't depend on the success. Like a dessert at the end of the meal: great but not quite main course.
