When these events fire they send specific arguments relating to the event.
You can find these arguments on roblox reference & documentation.

The parameters are the variables for the connected function which are assigned the value of the arguments passed by the event triggering this function.

For example .PlayerAdded sends the argument Player, which is equal to the player instance which triggered this event to fire.

The .Touched event sends the argument otherPart, which is equal to the other part which was touched, triggering the event.

Basically parameters are variables which can be assigned within a function each time a function is called

And in roblox events, these are usually relating to the details surrounding the event
