No it isn't; numbers are a map, maps are not the territory. You are asking me to define how a map is different from a city, but you are not accepting that the city is made of concrete and is square kilometers large and the map is made of paper and is square centimeters large as a meaningful difference, when I think it's such an obvious difference it's difficult to put any more clearly.
What constitutes a real atom: a Hydrogen atom capable of combining with Oxygen to make water, capable of being affected by the magnetic field of an MRI scanner, etc.
What constitutes a simulated atom: a pattern of bits/ink/numbers which you say "this is a representation of a Hydrogen atom", capable of nothing, except you putting some more bits/ink/numbers near it and speaking the words "this is it interacting to make simulated water".
