Correct terms would be "hopefully fair" and "result calculation by TX ID" (with no correlation between the two)

Overall, it's just that the bitcoin community loves the "Don't trust, verify" mentality with bitcoin itself, but also with gambling sites. RGBKey was merely trying to say that your solution isn't provably fair (at all) especially after you said "it's the best provably fair option" lol. Obviously if it's not provably fair, you can't promote it as such either.

Anyway, I don't think you had/have any bad intentions or that you are trying to cheat anyone. It is just that it is really not provably fair (and TBH you were a bit ignorant about it in this thread - RGBKey made some of the first verifiers back in JD times lol, he isn't some random shill.) But sounds good that you will improve the system I think a nonce-method where you give a hash before the first bet and ask the player to give their client seed would be perfect with this Telegam setup.
