Is the top pointer top in the linked list the same as the traditional pointer? Do they all store addresses?

Essentially the same, but there are some differences:

1. The stack top pointer TOP points to the top of the stack (the tail of the linear table), and the linked list pointer points to the head (or head node) of the linked list.

2. The stack is generally not set, and the top generally points to the top element of the stack; Linked list structure is divided into two types: leading node and non-leading node, so linked list pointer may point to header element or leading node.

3. Nodes have the same composition, but different meanings. From the table, the two are opposite. Look at the picture below:
