First things first, your channel needs to be eligible to get a YouTube custom URL. Your channel needs to have 500 or more subscribers, be at least 30 days old, have an uploaded photo for the channel icon, have uploaded channel art, and, on top of all that, needs to be in good standing. If you meet all of these criteria, or are extremely close, then you can start thinking about your custom URL. This is why the custom URL on YouTube is a sign of prestige; you must have at least 500 subs to be eligible. It’s an awesome milestone to reach, but also a daunting one, as this decision cannot be reversed once finalized.
It has been 100 subscribers for some time. I have no doubt it would have been 500 subscribers at some point in the past though
