You got a nice designer; welcome to the forum. It seems recently a couple of gambling platforms' slogans are 'no KYC'. Definitely we welcome this kind of non-KYC gambling platform on the forum. We know forum users really care about their privacy, and you are going to provide a non-KYC platform. So I believe if everything else remains smooth, you may get a number of users from the forum.
You just need to make sure games are fair; if it's a user-to-user game, then there shouldn't be any issues, as you said. Another important thing is withdrawal; people are always concerned about this. So you must need to focus on fast withdrawals. For the rest, we can see reviews from the users when they start using your gambling site. Good luck.
