I don't get the last point. What does being white or well off have to do with the ability to write books people wanna read?
Or is this just casual racism disguised as an attempt to virtue signal?

For actual ability, nothing, though the knock-on affects of being white and thus having a higher chance of greater economic standing from birth onwards, higher chance of good education opportunities, greater likelihood of good nutrition, and all the other aspects of existent systemic racism means that ability to have time to write is greater for white people (in the USA).
Pointing out the reality of systemic racism is not racism. Institutionalized white supremacy is very real in the USA and is so inherent it can have weird effects like how children prefer to play with white dolls: https://www.history.com/news/brown-v-board-of-education-doll... (it turns out this still happens today). So it follows that white women, for the same reason, might have an advantage on social media accessed by people living in a white supremacist system, or a system that still holds echos of white supremacy.
Others in the thread have posted some links to statistics.
But, this is not to say that there are not exceptions. There are some white women that have written good books, and there are non-white women that publish good books.
It was just observation on a general trend. There is a group with free time to pursue 'something' that doesn't make a lot of money because of the status they get from that 'something'. Hence they have a lot of influence in that market.
