Hello, I am a first year student studying commerce/biomed and I have just received my 2nd semester results and they weren't what I was hoping for to say the least

For the first semester I had passed all my units (4 units) however this semester I have managed to not pass 3 out of the four 😢. From my understanding, my progression is not considered unsatisfactory and will not be contacted by the academic progress committee as I have passed more than 50% of my units for the year correct ?
What is the likely outcome for such a matter? I know people receive warning letters however is that only for mid year as they would be in risk for the unit passing for the 12 months ?
Also, do you the uni send any sort of emails regarding your fails etc, I haven't received anything and I'm very concerned.
Thank you!
Edit: does Monash Usually send such letters in the mail regarding warnings etc, or email on the day of results?
