SoloRenektonOnly is the youtuber / streamer you want to subscribe to. Don't be misguided by name, he plays a lot of champions and does that for entertainment mainly. But is very informative as he usually talks loudly about his thought process before he makes stuff happen. He's not master's but mid diamond player. So most of what talks are relevant stuff basics like trading patterns, minion wave manipulation, recall timings, gank set ups etc.
Another good one is Neace, for better understanding of the game in general. Level-headed master tier player. Who focuses more on lower elos.
Basics: lane is won and lost by minion wave manipulation. This will effect your recall timings, security versus ganks, trading effectiveness, pretty much everything. What you're looking in general is usually to accumulate a lot of small advantages which you later convert into big ones. Early all in's happen, but either it's very match up dependent (darius), specific type of cheese (tryn, wukong), or has at least 1 player who is somewhat clueless about whole thing in general. This might be the big difference from mid lane, where kill pressure becomes high after one successful trade and is perhaps more champion mechanics dependent than top lane.
Tip: oh and expect gank at 2:30~3:00 meaning, don't set yourself up with a minion wave in a way that exposes you to early 1v2 versus a jungler with double buffs. Jungler will usually start bottom where he can get a stronger leash by bot lane, clear 2 more camps and come for you.
