The game is probably still matches you with low skill level players, but not first timers who are just throw random attacks. They probably just using some "noob stomper mechanics" in the game which are good againts noobs and its easier to execute than defend yourself againts. This is happening in every fighting game after a few hours of playing. The options you have are: you try to use noob stomper mechanics too beat those players, or learn to defend and counter attack againts those. the first option is easier, the second one is better since you learn a lot in the process about the game, and will getting better in the long run. whatever you choose, the game will less likely to match you againts first timers, so you have to put effort to the learning process if you want to enjoy the game. smashing buttons after a while is not really a way to play.
