Ferrari lost speed during that race and Vettel lost many positions.
Let's add some context, as I see you're getting on Vettel's case again.
Vettel qualified with a lap record
He got away in first
He was left exposed to Bottas by Kimi, who had a poor start
The Ferrari team's strategy let Vettel down when he was undercut successfully by Bottas
The Ferrari team's strategy let Vettel down by not pitting him during the safety car, or had no opportunity to pit him during the safety car. Take your pick. Interestingly, Mercedes could have pitted Hamilton but chose not to
Vettel was now left exposed to the Red Bulls, much faster than anyone else due to their fresh tyres
Ricciardo overtook Vettel on his much faster tyres
Verstappen, who at this stage of the season was very much at 'peak Max', hit Vettel while trying to overtake him on his much faster tyres
Verstappen was penalised by the marshals for this incident
Vettel suffered damage to both car and tyres
Vettel was subsequently much slower
Even Alonso in a lol McLaren subsequently overtook him (with some relish and abruptness, I recall)
So context is quite important to the statement that you made.
