It is the average time taken per operation over a large sequence of operations, smoothing out the cost of rare, expensive worst-case events.
Because 99% of insertions take O(1) time, but occasionally the array runs out of space and must perform an O(N) resize. Amortized analysis proves the average cost remains O(1).
No. Pure O(1) guarantees every single operation is instant. Amortized O(1) means it is instant *most* of the time, but you will occasionally experience a slow operation.
