Am a fresher, this guy is leaving the team, so they hired me as a intern saying ill be taking his tasks and he trained me in few days and left?

Now after a month they hired a new girl with 10yrs of experience and said she will be replacing the guy and she will be initially doing all tasks that i am doing right now,
Now i have to train her on whatever the other guy trained me on, am afraid they have used me and they won't give me a permanent role
I feel really used right now
should i be worried or not?
Updates
+1 y
But the new girl is sweet and is giving me deeper knowledge about the whole thing
