does anyone actually win at blackjack without tracking anything

playing blackjack for years but never tracked a single shoe or tried counting cards. just the basic strategy and going by gut feeling. i know all the odds favor the house long-term, but every table has at least a couple loud folks claiming they're up for the week or month just by “feeling it.” not buying it but starting to wonder if maybe i'm missing something. poker i get - skill matters - but blackjack? without tracking? feels like pure luck unless you really tweak bet sizes or chase streaks, but that's usually how people lose faster. anyone stick to base game and actually show profit?
