Hello Aspirant,
Yes of course you can earn a great amount of money from YouTube, what you need is a content means you have to start a channel based on the niche you like and on which you can develop the content in video format, and then you have to upload the videos on YouTube.
Your earning starts when your channel will become eligible for monetization and for this you need to have minimum 1000 subscribers and at least 4000 hours of watch time. When you complete these milestones then you have to apply in Google AdSense for monetization of your channel. Then by running ads on your video you can earn money.
I hope this information helps you.
Good Luck!!
