A rolled fried tortilla makes a taquito or occasionally a flauta around here. Tacos are distinguished by being open-topped and served in such a way as to be consumed as finger foods (albeit somewhat messy ones for the better tacos), which your pictures definitely aren't.. that particular serving style actually looks a lot more like an enchilada plate to me, served dry for some bizarre reason. The rest of the preparation sounds right, the meat and dressings are just stuffed inside an open tortilla instead of rolled into a fried one.

I suspect probably 'taco' also has uses as a generic term for 'anything served inside a smallish tortilla', as opposed to burritos that use much larger tortilla rounds.
