Yes, ignoring any tax requirements because I'm not a tax attorney. You have to have 100k Robux (Rb) to initiate a withdrawl, that 100k Rb costs 1000 USD (ignoring any bulk deals they may run) to buy if you just purchased it from Roblox, but when you sell it to Roblox for USD you get 350 USD. So depending on how you look at it it is worth either 1k or 350 USD. The article was using 1k as the frame and it's what it would cost you to get that much buying directly so to me that's the most accurate.
