Lately, it looks as though those terms are now being used to reference anyone people just don't like.
Case in point: Poor Rey from the latest Star Wars trilogy. She has been called a Mary Sue because she got control of the Force really fast, and is also a good fighter and pilot. I agreed with these complaints at first. Then, someone pointed out to me that Rey hasn't done anything that Luke himself didn't do in the first trilogy. Also, Rey spent years on Jakku, so she probably picked up her fighting and piloting skills there.
Another example: Mon-El from Supergirl. Now, a lot of people don't like the character at all. However, some have even taken to call him a Marty Stu. This makes no sense, as the show has gone out of its way to not only show his imperfections, but to also have all of the other characters call him out on them. If Mon-El is a wish fulfillment character for the writers, then they apparently wish they were frat-boy screw-up characters that get yelled at for every mistake they make, do absolutely nothing right and piss people off come from a slave-owning kingdom that almost took over Earth, lose basically every fight they get into until recently, and face racism from their love interests of all people.
Finally, there is Skye/Daisy from Agents of SHIELD. She may or may not be an inversion, as she was called a Mary Sue in the first season when she was just annoying everyone (the writing for her back then may be a big reason the show lost so many viewers after a few episodes). Afterwards she was a seasoned agent who gained powers in season two, the leader of her Secret Warriors in season three, and was even the leader of the agency in season five. However, the show made it clear that she wasn't ready and now Mack is leading.
In the end, it all comes down to personal opinion. There are some characters who are Mary Sues, but there is a difference between a Mary Sue and a character that just bugs people.
