Ive always wanted to become a bigtime youtuber in the gaming scene, From 3 videos i made in the past making Minecraft Factions episodes i made 35 subscribers with roughly 200 views on each upload, since then i have gotten bored of Minecraft, removed minecraft content and moved to Call of Duty and am looking to create more content there to hopefully expand my content to a larger spectrum of viewers.

So my questions to you guys is;
Should i keep making content?
Is it too late to become big in the Youtube community?
From when (subscriber count wise) would you know you can start relying on youtube to make an income
