You can’t say for sure. My house has a gas stove and a 220v outlet for an electric stove. Most houses are wired for an electric stove even if it has gas, because not everyone is going to want a gas stove and wiring an outlet is easier than running a gas line.
If the kitchen was made for gas, it’s pretty unlikely there is a 220v outlet for an oven there.
