You have the wrong mindset. The majority of players you'll encounter in public mge are barely sentient and play like a reinforcement learning AI thats in the process of being trained to maximize elo gain, so you really have to go into it with one of two mindsets:
Mindset one is the bot map. You have to practice hitting airshots on the bots. Sometimes they're programmed badly and do weird stuff, but that's OK, you don't have to worry about what they're doing or whether you hit 20 first because you're practicing hitting airshots.
Mindset two is "going to the zoo". This is where you're joining the MGE server to observe the behaviour of all the different animals. I think this one's fairly self evident but it's the opposite of the bot map mindset where all you're interested in is the fascinating behaviours the other player is exhibiting.
Hope this helps and good luck in your future mge endeavours.
