真的随机起来，每次画的会不一样，你的圆怎么放？

像你那图，就自己随意手动指定一些点然后把它们 smooth cycle 地 plot 起来就好了，像这样 
\newcommand\dian[4]{\coordinate[label={#4:$#3$}] (#2) at (#1);}
\tikz{
\dian{0,0}OO{-90}
\dian{-160:2}AA{180}
\dian{20:2}BB{0}
\dian{-0.1,1.2}CC{90}
\foreach \i in {A,B,C,O} \fill[red] (\i) circle (1pt);
\draw (O) circle (2);
\draw plot[smooth cycle] coordinates{
(B) (50:1.2) (C) (150:1.3) (A) (-120:0.8) (-30:1.5)};
}

稍微调整到看起来没超出就行了，我上面的图在 A、B 处肯定不是真相切的。

你这个是 node ，和 label 是不同嘀。
可以用 every node/.style={font=\scriptsize}

你这图编译起来有点慢，用那么多 plot 还需要算三角函数，有点浪费资源了。

用画图那个，画得快就会光滑些，反正这种图又不用画精确。
而且画完后可以编辑，选中它，点 To Curve ，可以调整路径上的点（绿）和控制线（灰）什么的：
