You should have first clarify what crypto gaming is. If it is play to earn then it is not gambling but more of an investment. There's no betting procedures in p2e. The only some sort of gambling in such kind of game is lack of assurance to be profitable in a long run but that's way different.

Would it have impacts to gambling industry? I doubt. If P2Es would allow betting in form of player to player match, it might indeed make more sense but that's not something new in gambling industry. It'll just be in form of another kind of game but p2p exists already in this industry for years.
