Got it, I'm just thinking there might be just 1 collision happening at one point in the future, even with the chances so small. I mean, again, it's VERY close to 0 but there still is that one very little chance of collision, right?

There are mathematical numbers that are very Very VERY small. Even though those numbers are not mathematically zero, they can be considered to be zero in the real world.

For example...

You sit in a large room full of air at 23 degrees celsius. The air is a typical earth atmosphere (a bit more than 14 pounds per square inch) with approximately 78% nitrogen, 21% oxygen, 0.9% argon, 0.04% carbon dioxide, etc.

The oxygen molecules bounce around RANDOMLY in the room. mixed together with all the other molecules in the room. If we consider EVERY possible arrangement of all those air molecules, each of those arrangements is equally likely as any other. However, there are many, Many, MANY more possible arrangements that result in enough oxygen being near the air holes in your face to keep you alive than there are arrangements that result in there being no oxygen at all close enough to keep you alive.

So, in a normal room, with a normal amount of air, there is a mathematically NON-ZERO chance that you will unexpectedly, and suddenly die of suffocation for no apparent reason (just because the oxygen randomly happened to end up too far away for you to breath it).

However, in the REAL WORLD, I think any reasonable person would say that there is ZERO CHANCE of that actually happening.

Another example...

There is a non zero possibility that you could be struck by lightning once a year while sitting on a toilet taking a crap every year for 17 consecutive years. I think any reasonable person would also say that there is ZERO CHANCE of that actually happening as well.

What about LBC? I have never used it before although I did want to, but it seemed kinda sketchy to me.

It's a sketchy scam.

However, I've seen lists of Bitcoin addresses found as collisions with older transactions on them or even still having BTC on them. How does that work, aren't they privkey collisions?

Sort of. There is a difference between a private key that is actually chosen RANDOMLY, and a private key that is not random at all.

Lets say I choose to use a private key with a value of 1. The odds that someone else will decide to try the same private key are pretty good. It is not a randomly chosen number, and it is therefore very likely that someone else will also non-randomly choose that number.

There are a number of private keys that have been chosen (non-randomly) in the past by various people for a variety of reasons. The fact that LBC which also chooses private keys non-randomly happened to try some of those same private keys is about as surprising as the fact that there is more than one person in the world named Peter.
