No, they trained more Threes. The number is the "model" of Spartan if you will. Kurt trained a bunch of threes, they all died, he trained another group, two survived, and then we have the plot of Ghosts of Onyx.

Spartan 2's are supreme badasses stolen from their families at 6 and horribly expiremented on. They're also the strongest.

Spartan 3's are older childern orphaned by the Covys and given a "chance for revenge". They have minor modifications and are still pretty badass.'

Spartan 4's are ODSTs in power armour.
