The screenshot shows something different.  I answer the screenshot:

Depending on the mode, start isearching using word or symbol mode (M-s
w, M-s _) enter you search term and then M-% to query-replace the word or
symbol.

"Depending" means it depends on the syntax table of the current mode if
that is exactly what you want, or more, or less matches.  And if I
guessed correctly what you want.
