No. Lesbian means you only want sex and romance with women; strictly no men or boys at all. If you like both men and women, that means you're bisexual, which is not lesbian, and not straight, nor is it "both". Bisexual is its own specific orientation, like gay or straight.
The things you mentioned you're into, I'm a 40 year old woman and I was into at your age. I am still into them. I even started my own women's major league baseball team - that's baseball: Not softball. That's about as lesbian-seeming as it gets. Today, I work in a career usually mostly men get into, and am considered good at it. But I am only sexually and romantically attracted to straight men. What you are is a tomboy. When you grow up, you'll be called an Alpha Female or Alpha Woman.
I won't lie to you. This won't be easy. Your strength, sportiness and confidence will attract A LOT of gay women who think heterosexual women couldn't possibly be butch and like men. We do and can ;)
You will also attract A LOT of gay MEN. These will usually still be in the closet when they come on to you. They're attracted to how tough and interesting you are, how confident you are, and how your personality has a specific, hard shape - like that of a man. That will not mean they love or want to be intimate with you. But often they will hint that it does. It will become your job to gently guide these guys away from you, where their confusion has led them, back to where they belong - with other gay guys, dating THEM, not you.
Do not date a gay man. It won't lead anywhere positive. He will not stay with you in at the end of things; he desires the male body and though your brain and confidence are masculine, your body is female and nobody will be as aware of this as your gay buddy. Keep him platonic you'll be doing both him and yourself a lot of good.
The world doesn't offer a lot of safe or comfortable places to the very strong, fearless, confident, athletic and independent straight woman. Over time that will change. You are one of us: A future Alpha woman. One of the leaders. Watch your back for envious Beta chicks and their gossip and daggers. Look for the strong Alpha male tough enough and loving enough to handle you. I found mine and one day you'll find yours.
Being a strong woman who plays video games or even sports does not make you a lesbian. Desiring to have sex with other girls and with women makes you a lesbian. Nothing else does.
Be proud being a strong heterosexual woman. In ancient days they called us AMAZONS, girl.
Ride out on your war horse, shoot those arrows and conquer. :)
