Arduino Uno does not have built-in WiFi (But you can attach a WiFi module to it). ESP-01 is based on ESP8266 which does have built-in WiFi.

Without knowing what you are doing or how the two boards are connected it’s a little difficult to give a definitive answer to your question.

In that case, you should upload the code to Arduino.
