Hi there! I was told by an English teacher that this phrase does not need commas around "deep inside," but I have been unable to find definitive evidence regarding whether this is correct or not. Any help is appreciated.
"Moving has allowed me to view the incredible variety that the world has to offer, and it also has made me realize that, deep inside, humans have more in common with one another than one would initially think."
'deep inside' is a very brief adverb phrase. There is no need to separate such phrases from the rest of the clause by commas. CJ

I agree that you don't need commas, but it's not wrong to use them.
To my mind, it is a way of adding emphasis to the phrase. Try saying the sentence aloud, with pauses before and after 'deep inside'.
