What is third party in Binance?

Excuse me, could you please elaborate on what exactly is meant by "third party" in the context of Binance, the popular cryptocurrency exchange platform? I understand that Binance facilitates transactions between buyers and sellers, but how does the concept of a third party fit into this equation? Are there specific entities or services that Binance considers as third parties, and if so, what role do they play in the platform's operations? I'm interested in understanding the implications of third-party involvement, if any, on the security, transparency, and overall user experience of Binance.
