That's not how it works.
World of Warcraft free accounts cannot trade with other players, so there's no way to transfer the gold.

Many World of Warcraft gold sellers do run a scam and money laundering operation though.
There are 2 divergent processes from what I've observed.
1. Credit card fraud using gold.
- Buy bulk skimmed credit cards from Russian criminals.
- Buy World of Warcraft accounts to do their business with.
- Sell the gold on their website - needs a payment service provider for customers to pay them.
- Buy the gold using the credit cards - they use the facilities of Blizzard or other resellers like kingpin, etc to buy gold.
- Deliver gold that was purchased on their website to person A (a website customer).
- Sometime later, the original credit card owner performs chargeback on his card. Blizzard remove the gold from person A.

2. Credit card fraud again using prepaid game time.
- Buy bulk skimmed credit cards from Russian criminals.
- Buy World of Warcraft accounts to do their business with. using the stolen credit card
- Sell 30 day prepaid gametime for gold in-game using /2 trade chat.
- Buy 30 day prepaid gametime from kingpin, g2a, etc using the stolen credit card when buyers are found.
- Deliver the prepaid gametime to person B in exchange for Wow gold.
- Sell the gold on their website - needs a payment service provider for customers to pay them.
- Deliver the gold that was purchased on their website to person C (a website customer).
- Sometime later, the original credit card owner performs chargeback on his card. Blizzard removes the gametime from person B.
