Yes, this is true. However it doesn't call those characters
"operators".  Are you implying that all of the characters in section
2.2 with special meaning are operators? The first mention of an
operator is in section 2.1:

    The shell breaks tokens into words and operators. See section 2.3

which then says:
    If the previous character was used as part of an operator and the
current character is not quoted and can be used with the current
characters to form an operator, it shall be used as part of that
(operator) token.
