EDIT: Regarding the question, whether or not the arrows are supposed to overlap:
Yes, it symbolizes a transition kernel, which takes the state Xt and action At as input and returns the next state and reward Rt + 1. I also added a dotted line in the top bit, because the actions can depend on the entire history in general, although the markovian behaviors are more important.
Don't worry about updating your answers. I just wanted to learn about ways to improve next time. You helped me a ton.

Since you asked is there a more elegant way to do this, here is a starting point to define the nodes using foreach
.
documentclass[margin=2mm]{standalone}
usepackage{tikz}
begin{document}
begin{tikzpicture}[%
node distance=1.5cm,
inner sep=2pt,
]
foreach [count=i] l in {-1,,+1}{
node (Xi) at (4*i,0) {$X_{tl}$};
node[right of=Xi] (Ai) {$A_{tl}$};
node[below of=Xi] (Ri) {$R_{tl}$};
}
node[left of=X1] (left) {phantom{$X_t$}};
node[right of=A3] (right) {phantom{$X_t$}};
%% dashed line
draw[dashed] ([yshift=7.5pt]left.north) -- ([yshift=7.5pt]right.north);
begin{scope}[%
->,
rounded corners=5pt,
thick,
]
%% X to A
foreach i in {1,2,3}{%
draw (Xi.north)
-- ([yshift=7pt]Xi.north)
-| (Ai.north);
}
%% X to X
draw ([xshift=4pt]X1.south) -- ([xshift=4pt,yshift=-7pt]X1.south)
-| ([xshift=-4pt]X2.south);
draw ([xshift=4pt]X2.south) -- ([xshift=4pt,yshift=-7pt]X2.south)
-| ([xshift=-4pt]X3.south);
%% X to dots
draw ([xshift=4pt]X3.south) -- ([xshift=4pt,yshift=-7pt]X3.south)
-- ([yshift=-7pt]right.south)node[right]{$dots$};
%% A to dots
draw (A3.south) -- ([yshift=-7pt]A3.south)
-- ([yshift=-7pt]right.south);
%% A to R
draw (A1)
-- ([yshift=-7pt]A1.south)
-| (R2.north);
draw (A2)
-- ([yshift=-7pt]A2.south)
-| (R3.north);
%% dots to X
draw ([yshift=-7pt]left.south)node[left]{$dots$}

I improved it by using node
and taking advantage of these nodes' .south
and .north
– this would make the texts have a better spacing with the arrows. Also, a variant of the format of the arrows is used.

Since you asked is there a more elegant way to do this, here is a starting point to define the nodes using foreach
.
documentclass[margin=2mm]{standalone}
usepackage{tikz}
begin{document}
begin{tikzpicture}[%
node distance=1.5cm,
inner sep=2pt,
]
foreach [count=i] l in {-1,,+1}{
node (Xi) at (4*i,0) {$X_{tl}$};
node[right of=Xi] (Ai) {$A_{tl}$};
node[below of=Xi] (Ri) {$R_{tl}$};
}
node[left of=X1] (left) {phantom{$X_t$}};
node[right of=A3] (right) {phantom{$X_t$}};
%% dashed line
draw[dashed] ([yshift=7.5pt]left.north) -- ([yshift=7.5pt]right.north);
begin{scope}[%
->,
rounded corners=5pt,
thick,
]
%% X to A
foreach i in {1,2,3}{%
draw (Xi.north)
-- ([yshift=7pt]Xi.north)
-| (Ai.north);
}
%% X to X
draw ([xshift=4pt]X1.south) -- ([xshift=4pt,yshift=-7pt]X1.south)

%% X to dots
draw ([xshift=4pt]X3.south) -- ([xshift=4pt,yshift=-7pt]X3.south)
-- ([yshift=-7pt]right.south)node[right]{$dots$};
%% A to dots
draw (A3.south) -- ([yshift=-7pt]A3.south)

I improved it by using node
