I would absolutely LOVE it if they played ANY of the money back 
It hasn’t happened. The last one won $3.5k total with $400 buy in’s. Cashed out and hasn’t played since.
Previous month it was about $2.5K with a $50 buy in.
I’d have to look at the other ones, but these have been typical ever since the second month that I had a ‘whale’ and every month since.
