What are their exact roles, im particularly confused on the role of rRNA.

In short:
tRNA are transporting amino acids to the ribosomes (t stands for transport), while the rRNA (r stands for ribosomal) are lying on the ribosomes where rRNA are forming amino acids to chains of polypeptides (with the help of mRNA strands), so proteins.
To sum up: tRNA has the function to transport amino acids, while rRNA connect them to proteins.
Here is a picture of it: tRNA and rRNA .
Hope that gives you a good overview.

When tRNA brings the amino acid, the rRNA in the ribosome helps to form peptide bonds between amino acids. The tRNA will leave after releasing the amino acid and the next one will come in.

During translation, the mRNA is attached to the ribosome. tRNA has anti codons that match complementarily to the codons on mRNA. each tRNA molecule also carries one amino acid.

Very precisely in your short explanation! even more precise than mine. Boy, have forgotten to mention the codons and anti codons.
