Could you do this with CNC, probably, but ideally you've probably got someone hand carving the mold masters. How do you mix colors that people are actually going to want to use. How do you mix the clay such that it can last in a casino being used every day without losing color and not falling to dust. Then you have to learn how to operate the machine and produce a product that people actually want to buy. Time, money, and the right skillset and sure. For something like that, a machine that's been running probably pretty smoothly for decade after decade I'm sure there are a lot of things you could reverse engineer and figure out and some you'd just have to learn the hard way, but yeah, you COULD do that. So if you wanted to 'make one in your garage' you could crawl in and out of one and recreate it. They still work and people still use them, but the companies are long gone or are completely different, think IBM.
The machines that people use haven't been made in sometimes 100 years.
