Yes.

To be pedantic, '*' matches any node that is of the 'principal node type' for
the given axis. The default axis is 'child', so match="*" really means
match="child::*". The principal node type for the child axis is element, so
yes, "*" matches any element node.

The attribute and namespace axes have a different principal node type, so for
example "attribute::*" or its shorthand "@*" both match any attribute node.

node() matches any node at all, but match="node()" means
match="child::node()", so it only matches nodes that can be children, which is
all node types other than attribute, namespace, and root. So yeah, you got it.
