Yes, pro's would roll 300 after 300 on a typical house pattern. It wouldn't be interesting. I haven't watched in many years but I recall they started to show on broadcasts the oil pattern being used (they had 6 different types and they each had an animal name I think) and the announcers would detail how the pattern needed to be played for different types of bowler styles and left/right handedness. Lefties always have an advantage because fewer people bowl from that side so the oil doesn't get pushed around as much and they can create a "channel" from their own shots that "groove" the ball for them. Each pattern has a different length down the lane (some are long, some are short) and different application of oil from side to side. A Google image search will show you examples. I've bowled on them and they are humbling for someone who reliably shot over 200 on a typical house shot.
