The exchange of information between 2 hosts occurs at the link level, that is, only mac addresses are needed for this, and the ip address is used to deliver a packet in different networks and it is used in routers, is this how the interaction takes place?

What is your question?

Commentary on the thesis about the data link layer: in the TCP /IP stack, two nodes located in the same segment of the local network are addressed by IP addresses. For example, 192.168.0.1, 192.168.0.2, etc.

The ip address is also used within the network. TCP /IP has many tasks besides routing. This is the control of message delivery and splitting the connection into ports. At a purely data link level, most of your applications will not be able to exchange data.
