You are right, most casino tokens are trading below $1. But here, it is not just the price, but the utility of the token and its integration with the platform that is more important. For example, Rollbit ($RLB) or BC.Game ($BC) they are building a whole ecosystem based on games, staking, lottery and revenue sharing.
A casino token without a utility makes very little sense in my opinion, it would hardly be bought, at most as a “share” in a (potentially) successful casino in the hope that it will be worth more at some point.
However, the casino tokens you mentioned all actually have a use and it pays off for anyone who plays frequently on the respective platforms to hold them.
This is certainly also the case with the Whale token. It certainly won't be long before the TGE of the $Whale token actually takes place.
Incidentally, TheStreet.com has dedicated a separate article to the $Whale token:
