when I was a kid, I had a unique gift for numbers and breaking them down into primes that led me to somehow competing on the county level for these weird speed-math challenges that were popular when I was young. I remember using a lot of tricks. Being able to quickly break down a number into primes by rote memorization was a thing I specifically remember being trained on. There are a lot of number tricks out there that you can train and speed yourself up. this made me quite successful in certain games of chance and odds based games that require quick mental arithmetic when I was younger. Some of it requires mathematical insight, for sure, to derive insight that leads to more speed - but arithmetic can be trained for sure.
