I don't think it would have reached that, but my main point is that people think that any manga that is popular and gets a good adaptation will reach 50 million copies or above in circulation, which hardly ever happens.
But Jujutsu Kaisen and Kimetsu no Yaiba were full of these "slice of life" moments. There were chapters like the one in which Yuta and Todo become "brothers" and some of the chapters of Kimetsu no Yaiba like their training arcs.
