Newbie Shooter

I know it’s not statistical but it seems Newbie rollers do well. I was playing at Hard Rock when an older gentleman approached table. He was respectful and definitely not a big spender 🤑 he would ask simple questions. As the game progressed I was staying alive but not gaining ground. (IN with $300 playing all box numbers. $10 table with $1 ante) The older gentleman was second to my left. He lost the $30ish he had to bet. My wife came to the table and was ready to go. I said we have to wait until the old man shoots. I spotted him $11 so he could play pass line and shot (First time he ever played craps) he went on roll!!! I was racking in the winnings unfortunately he was not winning much betting only the pass line . Now I was $700 out! ( my wife and I have a casino rule once you double winnings you can keep going but walk way when your back to double money) On the way out I gave the shooter $20 and so did another player. Experienced with Newbie rollers? Would you tip shooter?
