I would like to say that luck is only important in pre-flop all-in when you encounter a coin flip. But this is wrong to say, even the best professionals still depend on luck, of course with talent and discipline you will make fewer mistakes, depend less on luck and you will make more money and win more often. However, it is very unlikely that you will reach the top position in a big tournament without having to rely on luck at least a few times. That all-in check raise of yours that got called by a weaker hand that hits your 2 outs on the river, that your shove on a flop full of draws that doesn't hit anything on the turn or river and loses to your second pair. opponent had, even if only with the requests you had a better chance.
Yes, in poker, as good as you are, you're still going to need luck.
