I’m not certain exactly what YOU mean by rollers, but what is conventionally meant is a series of round drums that you can ride your bike on indoors. I wouldn’t recommend that. You already need delicate balance and a smooth pedal stroke BEFORE using rollers. If you are talking about a stationary trainer, I wouldn’t recommend that either. To learn to ride a bike, you need to be able to balance it. Bikes wobble and your brain needs to imprint how to counter the wobble. Everything else comes easily after that.
I would start on a slight grassy incline. Don’t even pedal. Just coast down the incline repeatedly balancing the bike. Once you get comfortable with that, try coasting and then pedaling. Then, just pedaling. Then, practice.
