I know some magic: the gathering players who did very well counting cards as part of a team. The “big bettor” sometimes worked in the way you mentioned but sometimes it was something completely different, like a crazy religious person who would bet small for a while while clutching a rosary, then When the deck was hot they would go douse themselves in a nearby fountain while praying loudly, then come back to the table, wet, and loudly claiming the Lord told them they were going to win big today and start placing max bets. Can you do this every night at the same casino? Absolutely not. Can you do it once, then switch to a completely different persona at a different place? Apparently you can, at least ten years ago. Edit: also, while the big vegas casinos do all this stuff properly, a lot of the small casinos on Indian reservations are more lax with their safeguards. The issue is that table maximums tend to be in the $500 range which makes the dollars per hour somewhat minimal.
