Larian was just trying to engage in some good-natured teasing. A bit of "haha, we gave you so many weird options but the most popular thing was super basic and normal, isn't that ironic?" There's no genuine criticism to be found.
Not sure if it even is a criticism. Sven isn't the first or only to point that out. Similar stats were released by Josh S. during PoE2 development.
If it's a criticism, I don't think it's a criticism of players and more of games themselves. As a roleplaying game it is about creating a fun character using options provided - if players opt to go for generic white dude then it could point to game's failure in encouraging players to roleplay and fully take an advantage of options provided.
Or maybe it's a maturity of the audience. I definitely go for more roleplayee characters these days, then when I started playing cRPGs. I defintely inserted myself in BG2 back in the day, even using my pic as a portrait. These days I would find that dull.
With traditional archetypes in media being white dudes it is not shocking that when creating a roleplayee protagonist players would still lean toward that option. With Origins BG3 does have opportunity to provide some compelling alternative protagonists and companions, though quality writing will be the deciding factor. An unusual companion or protagonist won't really sell anyone on the idea of they are not compelling characters.
