[Question] Question about RMXP event triggers

I get confused on Player Touch and Event Touch, what is the difference between both of them, sorry for asking it here.

Thanks in advance.

Player Touch: When you step on it (touch), that event will activate.
Event Touch: This works a lot like Player Touch, except it activates whether you touch the event, or the event touches you.

But you can also use Event Touch along side naming the event Trainer(3) and it gives the event "eyes" and you can then touch any tile up to the number in the brackets, providing you're in front of the event, and the event will play forward all the same.
