Not even close.
In fact, Serena is the one who claimed she could beat anyone outside the top 200. So this guy stepped up.
He was a chain smoker who smoked between sets...lol.
He claims he had a beer before the match--but nobody can prove it.

1998: Karsten Braasch vs. the Williams sisters[edit]
Another event dubbed a "Battle of the Sexes" took place during the
1998 Australian Open[33] between
Karsten Braasch and the
Williams sisters.
Venus and
Serena Williams, aged 17 and 16 respectively, had claimed that they could beat any male player ranked below 200, so Braasch, then ranked 203rd, challenged them both. Braasch was described by one journalist as "a man whose training regime centered around a pack of cigarettes and more than a couple bottles of ice cold
lager."
[34] The matches took place on court number 12 in
Melbourne Park,
[35] after Braasch had finished a round of golf and two beers. He first took on Serena and after leading 5–0, beat her 6–1. Venus then walked on court and again Braasch was victorious, this time winning 6–2.
[36] Braasch said afterwards, "500 and above, no chance." He added that he had played like someone ranked 600th in order to keep the game "fun."
[37] Braasch said the big difference was that men can chase down shots much easier, and that men put spin on the ball that the women can't handle. The Williams sisters adjusted their claim to beating men outside the top 350.

Anyway, even though she was already winning grand Slams, Serena was not at her peak way back then.
