If you are willing to use the Pythonscript plug-in (currently on 32-bit Notepad++ only), here’s a script that will enact your desired behavior. Running the script once will make it continue to work for the rest of the the Notepad++ session.

Here’s SelectedTextOccurrenceCountInStatusBar.py:

def SBROSMC(_):  # (S)tatus(B)ar(R)eporting(O)f(S)election(M)atch(C)ount
    if editor.getTextLength() < 10000:  # <---- limit functionality to files of this size or less!
        if editor.getSelections() == 1 and not editor.getSelectionEmpty():
            SBROSMC.match_count = 0
            def match_found(m): SBROSMC.match_count += 1
            def escape(s):
                chars_to_escape = r'][.^$*+?(){}\\|-'
                literal_backslash = '\\'
                search_str = '([' + chars_to_escape + '])'
                repl_str = literal_backslash * 3 + '1'
                return re.sub(search_str, repl_str, s)
            editor.research(escape(editor.getSelText()), match_found)
            notepad.setStatusBar(STATUSBARSECTION.DOCTYPE, 'Count of selection matches: {}'.format(SBROSMC.match_count))

editor.callback(SBROSMC, [SCINTILLANOTIFICATION.UPDATEUI])  # register callback

and here’s what it looks like running:

Note that due to what I mentioned before about how long this script could take to run for really large files, I limited it to file sizes of 10000 characters or less (totally arbitrary size selection, customize it at will to your situation).

Also note that the light-blue highlighting in the sample screenshot is something else of my own devising and will NOT be done by the provided script. :-D

If you have the ability to program in Python (or possibly Lua?) then the answer is Yes, it is possible (via the PythonScript/LuaScript plugins). I show an example of how it can be done here, with Pythonscript: https://notepad-plus-plus.org/community/topic/13087/sel-in-status-bar-is-off-by-1-on-line-count/8

A “count of instances of selected text” could cause a problem in really large files, as it would involve searching the entire file fairly often, which could take a great deal of TIME. If the files you deal with are relatively small, however, I would think this is very doable.
