Hello!
I made a program creating a dictionary, but the keys are random.
The issue is, I need to get the first element of this dictionary, but it won’t let me do dictionary[1] because it is not a list.
What should I do?

The dictionary part of a table has no notion of order. So nothing is first or second or last or whatever. You can instead do something like:
local t = {
{ key = "name", value = "Joe" },
{ key = "k", value = "v" }
}
print(t[1].key, t[1].value)
You can use the next function to retrieve the first item the dictionary iterator will iterate through:
local a = {}
a["test"] = 5
a["asdjh"] = "something"
local key, value = next(a, nil)
print(key, value)
