Can any woman chess player beat magnus?
That wasn't a very serious game. As for real tournaments, he obviously lost to some female players when he was doing his rating climb as a kid, but I'm not sure if Magnus had ever lost to a female chess player after he became a world champion. The current top rated female GM, Hou Yifan lost 5 classical games against Magnus and only got to draw one.

Magnus has only lost to 7 people since becoming champion in 2013.
Hou Yifan is the one who has the best chance to defeat him, but she has lost every single matchup against him. No other woman currently has the chops to defeat Mangus at this time.
I'd figure that Iga Swiatek has a good chance of beating Magnus if they played this year. Now if you limit the competition to the game of chess then things are different. Although anybody today has the possibility of beating Magnus at chess the probability plummets rapidly when you get below the top GMs.
A second coming of Judit Polgar circa 2005 would have a shot at scoring a win in a long enough match. The Polgar sisters were unique in their heyday but times have been changing and the likelihood of a latter-day player like Judit has been rising significantly (Yifan Hou may well be in the process of becoming at least as good as that latter-day player).
If you are willing to wait a number of years then Magnus' capability will decline with age and that would open the door to a number of top players.

Has this ever happened before? That a woman chess player beat Magnus Carlsen?
Has it ever happened before that ____ has out-preformed the best ____ of all time?
The answer in 99.999(etc)% of cases is "no." Only the super elite can occasionally outperform the greatest of all time. There are currently no super-elite female chess players, although Judit Polgar was formerly one before she retired, and she beat Carlsen in that casual game linked in the 2nd post.
Yeah, there just aren't that many who can beat Magnus, and the ratio of women chess players has always been low in all levels. It's not a problem of gender.

Yeah, it would require a long match... it took Anand 2 matches to beat Carlsen just 1 game. Karjakin beat him once in their match, but it was lucky (Carlsen was consistently outplaying him in their games). Neither Caruana nor Nepomniachtchi won a single game in their matches against Carlsen and Caruana was the #2 rated player in the world at the time of their match.
Like others said, gender has nothing to do with it. Winning a single game against the best is extremely unlikely for anyone.

Women are often worse players. I have no logic behind it, but I do have proof behind it.
WGM
WIM
WNM
etc.

Except there is no such thing as a male GM title. GM, IM, FM, CM are universal titles open to everyone.
The requirements for the W-titles are 200 points below the universal titles, but if you graph the FIDE ratings of male players vs female players, the gap is less than 50 points. The 200 gap was chosen in the 1970s, supposedly as a way to attract more female players.
