T5i would be a good choice. The auto focus will help you to easily film yourself (plus a fast SD-Card, get at least a 45 mb/s to make sure that the camera doesn't stop recording by itself).
You of course need a tripod and a proper microphone. Your only video that is uploaded so far has big sound issues.
Check out the Rode VideoMic Pro.
In terms of light I suggest a Softbox but I also saw many Youtubers with those "light rings". Not sure what they are called.
Check out my Channel for a Softbox Review where you can see what difference good light does and what to be aware of.
Other than that I recommend you to move away from that wall, it's boring and looks ugly on video. Look for a space with a nice background.
With the DSLR and Kit Lens (you need a STM lens in case you want to use autofocus) you will be able to create at least a slightly blurry background.
Also make sure to inform yourself about "head room", but that's of course a different topic, just noticed it in aour video and thought of mentioning it since you said you want to create amazing looking videos.
