I click the edges that is clicked in the tutorial 33:35 but when I press ctrl+b to bevel, nothing changes at all. 3:39 is what should happen but I just move my mouse and there are no changes. I feel like I've followed this tutorial very well at this point so I have no idea what is happening. This is so frustrating.

Solution: select all and press M > Merge by Distance:
And then you can bevel away:
