Question about the number of Egyptians

Hello Rabbi Michael,

I came across an estimate of the world's population at the time of the giving of the Torah, and they estimate that it was in the region of 40 million people. I asked how it was possible that the Israelites were almost a tenth of the world's population at that time (three million), especially since it was said of them, "The Lord did not desire you more than any other people, and chose you." And in general, from the estimates of biblical criticism that I have heard, they estimate the number of people who left Egypt to be in the tens of thousands (a number that is more consistent with historical data).
