Oceans are great at sequestering carbon, but that's via dissolved CO2 and ecosystems near the surface (which are not impacted by deep sea mining). The seabed ecosystem plays an ancillary role. Meanwhile, I'm not aware of any proposals to sequester carbon in seabed ecosystems. I'm certainly not qualified to analyze the accuracy of a soil science study or the field as a whole. As someone not in that specialty, the figure that jumps out at me is the 40x difference between the impact from ecosystem damage vs. other impacts. Generally that tells me that the potential for ecosystem impacts to nix the climate benefits of deep sea mining is low - it would require that soil science be so wrong that they missed over 90% of the carbon content of the seabed.
