First of all, you need not worry about you app being rejected because until it follows googles policies, it won't remove your app.
And the requirement you want can be fulfilled with this library. This will not increase app size more than 1 MB.
It also it customisable just like you want.
This is how you can implement it.
1.In your build.gradle, add this dependency
implementation 'com.pierfrancescosoffritti.androidyoutubeplayer:core:10.0.5'
2.In your layout xml file add the following code
<com.pierfrancescosoffritti.androidyoutubeplayer.core.player.views.YouTubePlayerView
android:id="@+id/youtube_player_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:autoPlay="true"
app:showFullScreenButton="false" />
3.In your activity add the following code
YouTubePlayerView youTubePlayerView = findViewById(R.id.youtube_player_view);
getLifecycle().addObserver(youTubePlayerView);
4.To load the video add this
youTubePlayerView.addYouTubePlayerListener(new AbstractYouTubePlayerListener() {
@Override
public void onReady(@NonNull YouTubePlayer youTubePlayer) {
//if your url is something like this -> https://www.youtube.com/watch?v=EzyXVfyx7CU
String urlToLoad = "https://www.youtube.com/watch?v=EzyXVfyx7CU";
String[] url = urlToLoad.split("watch?v=");
youTubePlayer.loadVideo(url[1], 0);
//if your url is something like this -> EzyXVfyx7CU
String videoId = "EzyXVfyx7CU";
youTubePlayer.loadVideo(videoId, 0);
}
});

If you are thinking that you can fully customise the UI,you cannot do it any way.This library also provides only option on the left and right side and the top and bottom of the pause/play button.It will look something like this.
