They all know, had to sit them down years ago and explain probabilities and odds to them. Given them all winners throughout the years. Helped my sisters through hard times with winners. Mom always asks me for a sport winner when she goes out to Vegas. I grew up next to Santa Anita Race Track, moms in her seventies I take her out to the Track on Sunny days. We've hit plenty of Exactas. Last football season was sitting with my girlfriend watching Monday Night Football, I asked her if she could go to the store for some milk and twinkies her reply, "Are you nuts we have $300 on a 3teamer with 2 winners and New Orl playing at home for the first time. I aint going nowhere." I didn't know she had picked up so much. All this accomplished after years of betting and losing and then learning and winning. If you can't make money gambling don't do it. Simple.
Oh yes, I hate the "how is the gambling going?" question, they always ask it after a big loss, never fails.
