Most of what we see in that dust devil is the elongated shadow of the small object due to the position of the sun relative to the lens. Tight little twisters like that can pick up more than you would expect, but not a person. Used to play with them as they crossed the local farmers field when I grew up. They feel warm, and you can tell the wind is cyclonic up, but at best it’s lifting like 2% of our weight. Kind of like standing over a pretty powerful fan or heat duct.
