Analysing the situation from an Operational System´s point of view, a correct conclusion is

a starvation occurs when multiple processes try to access the same resource at the same time.

when two threads need two different resources and each of them has the lock of the resource that the other need, it is a deadlock.

a lock occurs when one thread is still holding on to another resource that the second thread wants after it finishes.

a starvation occurs when the waiting process is no more still holding on to another resource that the first needs before it can finish.

deadlocks will only occur when two or more threads can be acquired in different times and they are grabbing no resources.
