I'm assuming these were actually lay pastors, and not ordained in any way?
I don't know exactly what you mean by "ordained." There are many different definitions - the church I grew up in has its own processes (and requires no coursework or anything of that nature).
All of the pastors at my childhood church were ordained (by the church itself; my uncle got "ordained" at a church down the street from me, and then went on to ordain others. You can become ordained by one of several online churches, for a small fee. My uncle paid $1000 for his ordination and took some classes at this church (which no longer exists; the leaders of the church were all self-ordained and have moved their base of operations to a more populated area).
Were our Youth Pastors ordained? I have no clue. But they came into town with the Evangelical Tent each summer. The Evangelical Tent was part of an inter-denominational summer program. I do know of ordained youth pastors though:
Not every youth pastor will get ordained - but here’s a glimpse into one youth pastor’s recent ordination process as he reflects on what it meant to him.

In the case of the first Youth Pastor that was actually employed by our church, he *was* ordained by the church and his goal (which he never achieved due to a whole other ball of wax) was to be a regular pastor.
A friend of mine was ordained as a youth pastor in the Lutheran Church (Lutherans require some classes in theology - he was a theology major and then after his bachelor's, he was a Youth Pastor, and then got a doctorate in dvinity and became a regular pastor. But not all churches operate like the Lutherans. Ours certainly did not.
The main pastor we had in my childhood had no college education, was a former boxer. He was ordained via this process (the one where he receives a calling, then a church calls that pastor and then the church itself ordains the man):
The head Deacon for this process was my boss and the other deacons were all men of standing in the church (they did their deacon thing each Sunday, which included passing the offering plate - they too were ordained by the church).
Right now, where I live, there are megachurches who do the same church-based ordination and they have ordination ceremonies for Music Ministers, Youth Ministers, Regular Ministers and Sunday School Ministry. Some of them ordain women, but the church I attended, sadly, did not. Some of these ministers do have a college background (at least a couple of years, esp. the Music Ministers, but many do not).
I had a very good friend who did the complex ordination path of the Anglicans: I've never attended an Anglican church where the priest didn't have a doctorate of divinity, btw (and even then, they have to impress the bishop and do more stuff to be ordained):
This was all really new and different to me, given that my own childhood pastor was ordained by my boss and his friends (mostly retirees from blue collar jobs, actually; one was a retired postal worker).
