Honestly there isn’t much to the “Patriots don’t have losing streaks” stuff. It’s really just math and probability. They win 75-80% of the time (with Brady/BB since 2001), so the odds are just very low that they’ll lose two straight games due to probability alone. In addition, they win well over 90% at home, so losing two in a row also practically requires two consecutive games on the road, which greatly narrows down the probabilities again. Losing to Houston has absolutely nothing to do with the Chiefs game. The Patriots lost two in a row last year, by the way, both road games, to Miami and Pittsburgh.
