Playing ranked as a new player

I started playing apex two weeks ago and finally qualified for ranked today, i was so happy until i played the first game. Two of my teammates were silver, I think both had mics, but no one said anything, and i was lagging so badly that i couldn't sprint. I decided to try again, on my second game there was no lag, no one said anything as well but at least i could play however, the skill level might be too much for me, i couldn't score a single kill lol so I think ill just give up on ranked and play unranked only from now on lol. If there are any tips on how to get better, i would really appreciate some guidance. I play on ps5 EU. Thank you.
