Electricity is the flow of free electrons. While there are chemical reactions causing such a thing (for example in batteries/akkumulators or the already mentioned biological systems), the vast majority of them don't.

So it is actually pretty far off to say all, or even most, chemical reactions are the same as electricity.

In other words: Chemical reactions can be the cause of electricity, but they aren't electricity.

What you can say though, is that both these things are governed by essentially the same set of physical laws if you look at their core mechanisms.
