No, industrial warfare (which is everything after say the invention of the railroad and certainly the invention of the steamship and machine gun) is / was won by industrial capacity.
The northern states were outproducing the southern states by something like 5 to 1 at the beginning of the war and that number go worse as the south's paltry industry was destroyed by union blockades and raids.
There is no way for the CSA to win that war. Their only hope was for the USA to simply vote against the war. Instead they re-elected Lincoln. Theoretically GB could have intervened and potentially inflicted enough damage to the US's war enthusiasm to knock them out but in that scenario the CSA becomes a british puppet. The fact that Britain had already outlawed slavery and was making more than enough profit off their holdings in India and Africa meant that was a fool's hope as well.

They had tried and failed to reach a political solution. The election of a Republican president was seen as the last straw but really the fact the union kept adding more states from the west who were all anti-slavery (because the majority of the settles came from the more populous and wealthier northern states) ensured the southern states would continue to loose elections

Industrialization had already begun and eventually the USA would have re-taken the land...or I guess the CSA could have fused with Mexico and presented somewhat of a united front against the union but the disparity in industrial power was going to become apparent eventually. The south (and mexico for that matter) relied entirely too much on agriculture to win a war against an industrialized power.
