Where are you from if I may ask? As far as I'm aware they are are pretty common, I know only of India which does them differently and maybe US / Canada? Although I think the point and the comma are switched in some countries, so a thousand Euros would be 1.000,00€
I think he is referring to the seperators after the decimal point, eg. the comma in "0.000,000,1". I have also never seen this. Although you rarely deal with such small numbers outside of math, where I'd usually write it in scientific notation or as a fraction (like 1/10,000,000).

I'm from the US, but I'm not talking about thousands separators in the whole number. I guess a better word would be thousandths separators.
