Not really, no card counter goes unnoticed forever. It's about making sure you get enough time to play when the count is high that you manage to earn money. If you're curious about the life of card counters I can't recommend this YouTube channel enough: https://www.youtube.com/stevenbridges
…because it’s actually extremely difficult to do with the countermeasures casinos now use, more decks and random cutoffs. Letting you try is very profitable though.
The whole environment part is of course not useful. None of the monitoring happening where you can see.
Which they rarely do now because the number of people able and willing to count a 7 deck shoe with a random cutoff is extremely small and it benefits them to let people try.
