"I've still got one more shot at it," said the 31-year-old Wolff. "So, head up high and look forward to Hockenheim. I didn't prove or show anything today. I really want to use that opportunity to show what I can do. To get into an F1 car is so difficult that you want to maximize it."
Asked why it had taken more than 20 years for a female racer to be given another opportunity in a competitive F1 session, Wolff told CNN: "Firstly, if there is no role model out there doing it, for all the little girls who come to the tracks and watch on TV, if they don't see a girl on track then they're not inspired to want to do that themselves.
"That then leads to the second problem that there's not enough girls karting or starting at a young age.
"But sometimes in life you just need a chance, and I got that chance with the Williams team -- Frank and Claire gave me that big break."
Williams -- who grew up in motorsport's macho environment -- told CNN: "I'm always a believer that it's up to individuals to come up and do it and that hasn't happened for whatever reason."
Giovanna Amati was the last woman to drive in the sport when she attempted to qualify for a race in 1992.
The Italian was competing in an era of F1 when there were only 26 spots on the grid and more than 30 cars pushing for those places.
Amati, driving for the Brabham team, attempted to qualify at three races but was not able to break through with a largely uncompetitive car.
Of the seven women to join the F1 world championship, only two have ever qualified to start a race.
The most prolific of these was Italian Lella Lombardi, who started 12 grands prix in the 1970s.
Lombardi made history while driving with March at a difficult 1975 Spanish Grand Prix, becoming the only woman to register a point-scoring finish in a grand prix.
The late Maria de Villota, who died last October, also began her F1 career along with Wolff when she was signed as a development driver by the Marussia team in 2012.
