How to remove intersection by overlapping?

Question

I want that if a label intersects any of my edges then the label is above the edges. I am also using Overleaf. I tried to fill the label white but it does not remove all intersections.

\documentclass{article}
\usepackage{amsmath}
\usepackage{graphicx} % Required for inserting images
\usepackage{tikz}
\usepackage{amsthm}
\usetikzlibrary {calc,positioning,shapes.misc}
\usetikzlibrary{matrix}

  \path[->] (s5) edge[bend right] node [mylabel] {0} (s4);
  \path[->] (s5) edge[loop above] node [mylabel] {1} ();
\end{tikzpicture}
\end{document}

after fill=white I got this

Welcome. // You could replace some edge[bend right] by to[in= ,out= ] AND enter suitable in/out angles. See e.g. here: https://tikz.dev/library-edges#sec-74.3 — MS-SPO, Jan 19 '24 at 18:05
The simplest fix is just to move \path[->] (s1) edge[bend right] node [mylabel] {1} (s3); to the last line. Then fill=white does what you want. — cfr, Jan 19 '24 at 18:14
@cfr I want to make lots of automatas like that so a general solution would help a lot — Coping Forever, Jan 19 '24 at 18:18
