Okay, well. First of all, have realistic dreams. To fund a casino, you don't need to know coding but you need to have capital and good connections for that. As you mentioned, you have capital. Then, you could hire HRs, developers, lawyers, register business in offshores, etc.
If you want to get all in one business, then seems the shady company (1xbet, 1xbit) offers betb2b platform where you get the whole ready things.
