Is there a difference between BPF and eBPF?

Short answer: no, same thing

Original bpf is a much simpler bytecode. Ebpf extended it and made it essentially x86_64 assembly (semantically). Then we all decided to call ebpf bpf for reasons.

Isn't it the case that you still need original BPF for seccomp?

The old classic BPF is still used by seccomp, but in the kernel transparently converted into eBPF. In the kernel we dropped the notion of eBPF and just call everything BPF (as the old classic BPF is pretty much a thing of the past and not extended / developed any further).
