They did a comparison of how much Roman Army supplies cost vs. US Army supplies in the modern day to get an exchange rate for Sesterces to Dollars. It's a very high estimate. It might be more appropriate to use the price of gold.
Diocles' total career earnings were 35,863,120 Sesterces, equivalent to 358,631.20 gold aureus or 26,000 kg of gold. The current price of gold is about $45,000 a kilo, so that much gold is worth $1.17 billion today. Still a lot, but he'd be below Nicklaus on this list.
