Well there are two big differences between my model and that car print. First exactly like you pointed out he painted the model straight onto raw print so every buildline is who isn't through the paint.
Second is that his model was printed on a desktop FDM printer in PLA material. My mech was printed on an industrial size SLS machine in HD Nylon so difference in resolution is vastly different.
But still, if I would to paint base coat onto that mech without priming and sanding it first you would also see buildlines on it.
You can sand the model without priming it at all yes but it would take you much longer because you would be physically sanding away the buildlines to make it smooth. What happens when you prime it first is that the primer is filling in the buildlines as it dries but also as you sanding it so you only require half the time to bring it to the same smooth finish.
Like I said I am using heavy build primer that is so finally dedicated to smooth models when sanded. Such primers are used on cars to repair body work etc. Primers, as they call them, that you buy in say Games Workshop in reality are just grey or black colored spray paint. There is literally no difference between them and your basic spray paint you can buy in any department store. They just call it 'primer' and charge double for it.
What you need is a heavy high build car primer. This is the one I use: U-POL HIGH/AL High5 Primer, 450 ml, Beige https://www.amazon.co.uk/dp/B003TQD5CC/ref=cm_sw_r_cp_api_II6lybPY0KDY0
