In theory Kakegurui is about gambling, but given the fact that the protagonist has what can only be explained as some supernatural ability to always win any roll or draw no matter the odds any tension is completely broken and interest on the story.
While the story has a lot of potential it is crippled with the absurd luck of the protagonist, it is also painful that other characters do not point it out at all or even bother to try to beat her.
My recomendation is to enjoy the visuals and disconnect your brain while reading do not expect any turns or anything like that.
