Pretty much all of Bolsonaro's allies have issued statements accepting the results. This statement by Flavio is more ambiguous, but given that most people from both sides have accepted the results, I still interpret it as a statement meaning "thanks, we tried, let's move on".

I could be wrong, but all signs are pointing to the results being accepted.

There's a chance these truck protests can grow and then a lot of the politicians go back on their statements. But I think that is unlikely at this time.
