bts made money too and bts spotify numbers shot up like crazy
within 1 year of dynamite, bts started pulling in 20m daily spotify streams, their ml started stabilizing around 35-40 million and lets not start with the post-dynamite merch collabs that keep on coming even till this day (the latest one being with lego)
Dynamite and Butter were special cases. Look at the main writers and producers form those tracks. There is specific reason why those tracks were given full out support by Columbia. Those were Columbia in-house productions, even the damn CEO had writing credits on Butter. Little to no production/ writing input from BTS and HYBE. So basically, Columbia made / will continue to make most if not all the direct profits from the music itself. Those songs were "promotions" for BTS the group. HYBE / Bighit / BTS really only made profit from the residual impact (improving the profile of BTS to the global stage). The strategy worked, but don't get it twisted that those were "BTS" songs that Columbia "promoted". They essentially sold their creative and financial souls for those two tracks. However, you are right. They make money on the after effects obviously from the success gained using those tracks.
