How big is small?

I’ve been watching the stock market, and specifically what’s going on with the Gamestop stock (GME). The media keeps saying “small retail investors” are driving the meteoric price change. I looked through WallStreetBets, the reddit feed where those “small retail investors” came together to plan and execute this action. Several participants post screen-shots of their stock positions, and I’m seeing cost bases/initial investments of $31,000, $94,000, and $142,000. Sure, there are many small fry with a few shares, but it seems the bulk of these “small retail investors” have pumped tens of thousands of dollars each into this stock. Should we be thinking of them as “the small guy,” or are they are just individual stock manipulators?
