No, globs are not regular expressions.

“Globs do not include syntax for the Kleene star which allows multiple repetitions of the preceding part of the expression; thus they are not considered regular expressions, which can describe the full set of regular languages over any given finite alphabet.”

You're right, normal globs are not regular expressions regardless of syntax. Parent is correct too, ksh globs are regular expressions. See shopt -s extglob in bash, setopt kshglob in zsh (extendedglob for zsh's native, IMO inferior, quantifier syntax).
