私はカジノ ギャンブルに慣れていないハイローラーです

You never encountered problems being stake-restricted by bookies? I have known dozens of cases of bettors who profit consistently who end up getting their stakes restricted, so they move to betting exchanges or a betting broker that gives them access to many bookies all at once, I never understood why bookies stake-restrict players when they build an edge on each market in their favor which is usually really high in small markets and a bit lower in highly liquid markets, they are making a profit anyways, what's the point of restricting?

Since you will play with really high amounts, I will recommend the big european casinos who we all know work with huge volumes: LeoVegas and Bet365. LeoVegas is exclusively a casino and Bet365 also is a bookmaker (which is their main product), these are the only options I can think of, LeoVegas was my favorite casino simply because I never had problems with them, if you verify your account before you start using it you shouldn't have problems, stopped using it because my country got restricted for some time but it's allowed once again. If you can register and play on crypto casinos I would recommend Stake, withdrawals are almost instant at least in my case, highest withdrawal I ever made was something around 4k USDT, not sure how it would go with higher withdrawals. Table limits on live games are incredibly high, to the point you will not even need to play on a VIP table (max bet 100k USD/EUR on normal baccarat tables by Evolution). Multiple currencies in the same account that can be switched at anytime (USD, EUR, CAD, JPY, etc). Bonuses are rakeback, monthly and weekly boosts which all work as a form of rebate and overall the casino seems to be friendly towards high-rollers. Only flaw I have seem is the daily race, I suppose streamers playing with sponsored money aren't excluded from participating, making the race unfair to real money players, which are the majority.

So in summary, I would recommend LeoVegas, Bet365 or Stake (if your country isn't on their restricted jurisdictions list)

LeoVegas is really strict with KYC! Before you make a deposit verify your account, all casinos require KYC sadly, I would also recommend not taking any bonuses, that way casinos have no excuses to reject withdrawals, if a player is verified and he never takes bonuses, there is really no reason at all to reject withdrawals, this is the best way to play. Since you are new to casinos I would recommend checking each casino T&C, specifically their AML, withdrawals and deposits policies, avoid bonuses if possible, try them first with small amounts and research them in review sites, unsolved complaints and user reviews. Good luck!
