First of all, don't let your teammates insult you, because if you say you have no experience, everyone will blame you for losing, even though I'm sure you're trying your best. When I first started playing Counter Strike, I downloaded the original 1.6 build https://all-cs.ru/cs16/sborki/cs16-english-original-version.html with a clear interface and maps to start practicing on bots. I gradually increased the difficulty and then asked my brother to play with me on the server so he could share his experience with me. I hope you can improve your skills.
