while in live casino, like playing roulette there is 15sec gap in every spin, in that 15sec i can think something, or sizing bets and close my gambling session for that day.
and also live casino's dealer is front of me i can see we are cheated or not, but i don't know if they use rigged roulette or not.
We still don't know if we are cheated though even in live casino dealer, we don't know if that roulette is biased to a certain number. And obviously casino's has the house edge in roulette, so the longer you play the chance that you might lose as well.
And here is a video of a live casino dealer cheating,

So in any case, there are still ways for casinos to cheat, just saying, whether it's supposedly provably fair or live dealer.
