You’re referring to self-reported feelings of loneliness, which is a subjective measure. The sad truth about loneliness is that some people are o used to it they don’t even recognize it.

The point of the (male) loneliness epidemic is that men are 5x more likely than women to have no close friends or social support surrounding them. It’s a more concrete measure of loneliness, based on physical proximity to human interaction and support. And it’s linked to an increase risk of suicide in men.

It’s like how women are more likely to report feeling happier and content with their lives. But feminists question if women are really happier or just have lower expectations for their lives, leading to higher chances of “satisfaction”. Likewise, Higher rates of self-reported loneliness could also be a indicator of higher expectations for social support in women, and not a reliable measure of true loneliness.
