Im an experienced dota player and i would never join an easy mode game because its too easy. (and carries get imba without good creepstats/herokills because theres 1extragold per second)
To get some experience try to play 5-10 heroes again and again. And if you know their abilitys really good take the next 5-10 heroes.
The most important thing at dota is the farm and the teamplay ability.
If you dont switch your lane you can have 8 creep kills per minute ( Nobody got these not even the pro players)
A really good farm is about 4-5 creeps per minute.
You should try to get at least 2-3 creep kills per minute so that you are able to afford some better items.
There are also many tutorial videos at different sites like playdota.com or simply youtube
You can also say /tips ingame to get some useful informations about your hero and gameplay.
If you have experienced dota players in your team, do what they tell you. You will learn much from their experience.
Hope this helps you a bit
