This was not clear in my post and I have now fixed it. Modified gravity is an alternative to dark matter. Under its simplest form, those theories modify Newton's laws at large distances. Note that you could build theories (and this is done) featuring both dark matter and modified gravity.

Is it clearer now? And thanks for the question by the way! ;)

Yes, well understood! And thank you for making it clearer.

My pleasure ^^
