is => a Token?
What is an issue for you calling the lambda expression (=>) operator as token?

Hi @LAN SHUHAO , Welcome to Microsoft Q&A,
The term "token" is more often used in the context of parsing and lexing in computer science. Tokens are the smallest units of a programming language. When a program is being parsed, the source code is broken down into these tokens.
Additional see https://en.wikipedia.org/wiki/Lexical_analysis#Token

All operators, keywords, variable names and some special chars, are tokens. This is generic term for parsed languages symbols and terms. see the c# grammar (which will include all token definitions):
