your definition of being rich might not be the same with his own definition of being rich and certainly, if you've stacked Bitcoin consistently for a period of 4 years, you're going to look rich regardless of how much you're using for your DCA.

If I'm earning $500 per month and I can afford to DCA $300 every month which for me is something that's 💯 realistic, by the end of the year, I have a groose Bitcoin that's worth $3.6k. Even without doing it for a period of four years I will look really rich because it's not eaey to be disciplined to the point of owning such worth of Bitcoin for a year considering that I'm only earning $500 per month. If I continue buying it for the next 4 years, I must have had at least $14.4k worth of bitcon for that period of time and definitely Bitcoin would have gone past $120k by that time which means that my $14.4k worth of Bitcoin should be at least  $25k. Now it's possible that Bitcoin might do better than that before the next four years or that it might not have gotten to that price which is the least possibility but regardless of what's the current Bitcoin price at the time, consistently doing DCA for 4 years is enough to have taken you to a Point that you might look rich. For others than earn way above $500k per month and can DCA with a larger amount, it's going to even be more advantageous for them.

Most investors that have the get rich quick mentality can't even DCA for a period of 4 years without selling thier Bitcoin. The maximun time some of them will leave thier investment before selling might just be few months and that's why they are mostly regarded as traders.
