It's both.

Those stats are very different depending on the social class. Men have fewer support networks in lower social class, but more in the upper classes. Given that we're talking about business owners, that's the range we're talking about.

Small business owners are hardly "upper class".

The equity involved makes almost all small business owners at least upper middle class.

I also wonder what percentage of men(or male business owners) believe they are in or have access to a "boy's club"

Given amount of people I've talked to that believe they pulled themselves up by their boot straps, and then find out they have a trust fund or where able to find a couple hundred thousand from a friends and family fund round, I'm not sure how much that stat matters.

It matters if you're painting women as disadvantaged by not being be part of one, but, say, 99%+ of men don't belong to one. Meanwhile, ignoring women-only support networks(like the kind that gives $5M to female business owners....)

The "boy's club" isn't a formal institution. It's not like something you carry a card for.

I don't think anyone ever thought it was

Yes of course, but that's not very relevant. OP is specifically addressing business support, not social networks.
