Using AI Voice vs Human Voice

I started my channel a couple of weeks ago and am using AI voiceovers from Murf AI. However, I am now considering using using a human voice and re-uploading the 2 videos that I have on my channel so far.

Do you think it makes a significant difference to the success of a YouTube channel when a human voice over is used as opposed to an AI voice over?

If anyone is interested in taking a look at my channel, I can dm you. I would appreciate any feedback or advice. Thanks!
