It also makes me wonder if everything is actually the same? I know it’s a silly question, but are all quarks the same (composition wise) if so, does that mean that at our smallest core, we are made up of the same thing? Does this also mean that if not, that there is always going to be variance even to our smallest level? I suppose this question is asking more about what exactly is the composition of the smallest possible particle, and is there really an end?

We don’t.
Quarks are not the same, there are 12 different types of quark (and anti-quark) in the Standard Model. They are similar, but have different properties.
It’s also important to note that when we get down to these scales ideas about “things” start to get a bit fuzzy. Systems can end up being more of a big messy ball of probabilities than fixed things with fixed properties.
