So I bought tickets from seat geek last night for my little man’s birthday. The price was pretty good should I be worried

So my kid is having a bday soon and he wants to see the Astros. I’ve never purchased tickets from a resale site. Should I be worried? Could they be fake? Did I pick a good section for him 106 lower level. How are the seat number set up? Ideally he would love to have his Peña jerseys sign. How can he improve his chance?
