She states that if she lacks networking, then she'd need to get by with wealth -- which then she follows up in a significant part of the article with why she doesn't have wealth due to taking up a less privileged career path.
You're mixing success in career with success in life (wealth/status). She's doing fine in her career path, right? If I want to be an accomplished historian of e.g. Tibetan architecture, I can know everything in that field, but it's probably not going to pay well because society doesn't care.
Then again, googling what "career success" means, the results say it's a personal definition, so maybe we're both wrong.
More like her lack of networking deterred her from getting the benefits of knowing people, benefits her peers can enjoy.
