Why is DNS over HTTPS more secure than DNS over TLS?

Why is DNS over HTTPS more secure than DNS over TLS?

According to this cloudfare article:

DoT only uses port 853, while DoH uses port 443, which is the port that all other HTTPS traffic uses as well.

Which, means that:

With DoH, DNS queries are hidden within the larger flow of HTTPS traffic. This gives network administrators less visibility but provides users with more privacy.

I understand this, but what difference does it make? Why does this make DoH more private or secure than DoT?
