1 in 635 chance of such bad luck happening is not that rare. However, what worries me personally is that I get similar odds a little bit too often. Especially if I play with increased bet sizes or if I am stupid enough to reverse a withdrawal. The thing is, you still should not get 1 in 635 odds every day but I feel this happens little bit too often to be random. Last time I busted 1000€ with 10€ bets when dealer constantly got 21 points hands with upcard 5 and all my double downs failed. There was maybe 0.5% chance of that happening and therefore I cannot prove anything but it is interesting how systematic this was as soon as I increased the bet size.
Right now I am investigating two runs at two different reputable casinos where I estimate less than 0.01% chance of such result. One of them is European blackjack where I had 88% return over 7000 hands played flat-betting. The problem is that it is very difficult to prove anything and Customer support already tried to shoot down my doubts with completely false arguments (for example saying that I had 97% return in previous sessions so that proves everything is fair).
