Success can also be relative. I am not a huge gamer anymore, but from what I noticed, this year wasn't really filled with many large releases yet and some that came out, like Diablo 4, are found out to be the soulless crap many more wise consumers expected it to be. So people might just be hungry for some quality games again.
Also the studio was already known for quality and some of their own brands were already quite successful, making them more or less the top CRPG developer that also brought a lot of innovation to the genre. Although Baldurs Gate certainly is a brand that draws additional people. I could imagine that their other games will also get in the focus again when people are finished with the new title.
That said, all the games you mentioned were a success I believe. Maybe not that large, but I think they all were "surprisingly" successful compared to many AAA titles that wished they were.
