This is good advice if he wagers real crypto. However, if he just wagers Funfury, he doesn't need to worry about losing because these tokens expire after 24 hours anyway. Regarding the Tower game, it is good with only one devilkin. I tried to play this game with 4 devilkins, but it seems unprofitable even if you want to reach only the second row.
I would guess that people are still sort of "careful" because they want to win something and in order to win that, you would have to actually have some tokens left. You could always try tomorrow and the day after that and it would never really be "over" at all, you get to keep trying it all throughout this situation and that is why I believe that we should not be really considering any of the situation as a problem if you lose it all.
Even in that situation, even if it is free, even if it is gone, there are some people who like to be in control of their situation and not get too overboard because that is how our brain is wired and we can't handle the chaos all that easily.
