How Come I Get Different Results From a TF Tutorial on my Machine?

So I am following a YouTube series here: https://www.youtube.com/watch?v=CA0PQS1Rj_4

And this person also posted their code on GitHub:
https://github.com/musikalkemist/Deep-Learning-Audio-Application-From-Design-to-Deployment/tree/master/4-%20Making%20Predictions%20with%20the%20Speech%20Recognition%20System

(I removed the model.h5 and data.json since I wanted to use a
model generated on my own PC)

I run the train.py which trains the model and get this as a
result: https://pastebin.com/mZSXK25v

When i test the “down.wav”, it predicts “right”: https://pastebin.com/Up8EvNyc

When I tested “left.wav”, it predicts “down”: https://pastebin.com/vzWzTV4X

How come I get different results, in fact completely wrong
results no matter what I test, despite getting a 0.9358
accuracy?
