saying HS is pure luck is always the excuse of the looser
if you play enough games you will realize this game has a lot of skill involved
us good players recognize this every month when we go back to rank4, when terrible players are all over the place, you can notice their poor plays and decisions every game. Actually is not until top200 legend when you can see flawless play.
Anyway, the only skill involved is basic math and reading. So please pat yourself on the back for having such things.
By your logic only skill in chess is reading (the rules), that's why no one, not even supercomputer and top AIs can play chess perfectly every time even when there are only 8 pieces left on the board.
